Good afternoon to all. I am planning on upgrading my current Unraid server with a new Asus LGA 1700 motherboard with an Intel 14900K CPU. My question is: What is the best way to cool the CPU? The Unraid server will be running 24/7. How hot will the CPU run streaming 4K video to one or two devices at a time? This will not be every day but on occasion. Normally, the server will see more use on the weekends than on weekdays. In my current set up, I am running several VM's and would like to be able to run a virtualized Windows 11 as my gaming machine. This will be later in the near future since I need to get a decent GPU first for gaming. I am debating between https://a.co/d/4jAC1Gi and https://a.co/d/g9Nqw3T to keep the CPU as cool as possible. Please advice on what my best option for cooling the Intel 14900K would be taking into consideration that it will be running 24/7 as an Unraid server, several virtualization machines but not running all the time, and ultimately a virtualized Windows 11 gaming machine. Thank you for your advice in advance.

Introduction Hey everyone! So I am fairly new to self hosting stuff at home, I am talking about 2-3 years here. I have bought my first Raspberry Pi about 3 years from now and my small home server 1.5 years ago. I first ran TrueNAS Scale as the OS, but switched to Proxmox VE, because I had issues with accessing other pods hosted on the same issue. Talked about this issue with one of my teachers back then and he advised me to install Proxmox instead of trying to fiddle around with IP tables and stuff. Since then I am a huge fan of PVE! Alright, so I then also started hosting other VMs on there, because I needed the unused computing power that I used for the pods on TrueNas Scale again. I started migrating some of my services onto an Ubtuntu-Server Docker instance. It's been like that since that point. Recently I started experiencing OpenShift at work and CI/CD pipelines with Tekton and wanted to also do something like that privately to strengthen my knowledge about k8s. I started researching and found the underlying project of OpenShift; OKD. Long story short; I checked the minimum requirements for OKD and realized that I am short of a few GB of RAM... My Goal I would like you to quickly take a look at the table 1 and 2 on the following official documentation: https://docs.okd.io/4.14/installing/installing_bare_metal/installing-bare-metal.html#installation-machine-requirements_installing-bare-metal For my cluster, I would need 3 control plane nodes and at least 2 workers. That would be a total of 14 CPU-Cores and 64 GB of RAM. I also have other VMs running on my system, that I have listed below this section. So there needs to be slightly better hardware, just to be safe. Current Specs Case: Fractal Define 7 XL Black CPU: AMD Ryzen 5 5600 G, AM4, 3.9 GHz, 6-Core RAM: Corsair Vengeance LPX, 4x 16GB, 3200 MHz, DDR4-RAM, DIMM Motherboard: ASUS ROG STRIX B550-A Gaming, AM4, AMD B550, ATX PSU: be quiet! Pure Power 11 CM, 600W Storage: - 2x Intenso top performance 512 GB, M.2 2280 - 2x Samsung 870 QVO, 1000 GB, 2.5'' - 6x Seagate IronWolf 8TB, 3.5'', CMR Other: - 2x Delock Host Bus Adapter 2 Port SATA PCIe - 3x Delock Molex to SATA power cable Virtual Machines NAS CPU: 1 Core [host] RAM: 8GiB [balloon=0] Storage: - 6x HDD pass-through - local-zfs (onto m.2) 32G virt. disk Docker Services (Ubtuntu Server) CPU: 3 Cores [x86-64-v2-AES] RAM: 14GiB Storage: local-zfs (onto m.2) 128G virt. disk Adguard (Ubtuntu Server) CPU: 1 Core [x86-64-v2-AES] RAM: 2GiB Storage: local-zfs (onto m.2) 32G virt. disk (The SSDs are currently unused, because I wanted to put the cluster onto those. Distributing the control planes and worker nodes onto them, having no ZFS pool for possibly a better performance?) Issues 1. My system was experiencing a high I/O rate, peaking at around 15-20% when doing high intensive writes. I had some MC servers hosted on there at some point, with large worlds and when they saved, all VMs were lagging to their death (almost). This was the case when I had the SSD1 and SSD2 as a RAID1 and I read that this can cause huge lag (possibly from ChatGPT, I cannot remember). Well so yesterday I migrated away from RAID1, also because I need more storage for my OKD cluster. 2. Another issue is that I had to buy those PCIe SATA adapters, because I didn't know that 2 of my 6 SATA motherboard connectors are going to get disabled, when using 2x m.2 slots. (I decided later that I am going to buy SSDs for my system). 3. Yesterday, a friend of mine pointed out, that my CPU only has 2 lanes and that this is probably going to be a bottleneck for my RAM. He advised me to do some more research about this topic though and as you can see I also don't know that much about hardware. 4. About the RAM issue, I would actually buy 2x 32 GB sticks here, and replace 2 of my 4 16GB sticks with them. 5. If I understood Proxmox VE correctly, it emulates certain CPU types, so the operating system would think that it has 4 cores, if I for example give it 1 socket with 4 x86-64-v2-AES cores. Also I still don't quite understand that part yet, with what CPU type to choose. Maybe I can get some advice here as well. 6. I actually want to give my NAS VM way more RAM, for faster caching, but it's not necessary really. Conclusion I would be very happy if I could get some advise about my current situation and maybe if you could address some other concerns that I maybe haven't stumbled into yet. I am willing to spend around 500$ for my upgrades (or more maybe, but I'll have to save up some more money then). I've also thought of maybe moving the NAS onto another Proxmox system (including the VM with the Docker services), but this will be more expensive. But this makes the system available for the cluster (with a small RAM upgrade).

I'm eyeing a used PC set for $130 (converted) with the specs listed below, and I intend on using it as my video editing NAS. i5-8400 8gb DDR4 (unknown if it's dual-channel and unknown speed) 128GB SSD (probably DRAM-less SATA) 500gb HDD 2x Rear ethernet ports (presumably both 1 gigabit) I plan on... Adding a PCIe x4 -> (2) M.2 adapter + (2) M.2 to (5) SATA adapter. Adding a 2.5gb ethernet port to PCIe x4 adapter. The prebuilt only has 1 hard drive bay and probably only 4 SATA ports on the motherboard, at least one of which is already occupied, so I thought to add more slots. I wonder if this setup will cause instability or bottlenecking. I also plan on running the NAS in a VM inside a Linux Mint install. I heard there are some amount of performance penalty when running a NAS on a VM, even with hardware virtualization enabled. Any thoughts?

Budget (including currency): $500-700 Country: USA Games, programs or workloads that it will be used for: Main Priority is a simple NAS + Homelab & Automation Management, Secondary Priority is a 1080p gaming PC (with VR in mind) or via Steam Link from other main gaming PC. Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): Intended Parts List (so far): - AMD Ryzen 7 5800X (owned) - bequiet! Dark Rock Pro 4 (owned) - MSI MAG B550 TOMAHAWK ATX AM4 MoBo (to buy unless suggested otherwise) - RX 580 8GB (owned, open to upgrade) - ADATA XPG Gammix D20 64GB (4x8GB) DDR4-3200 CL16 (owned) - Crucial P5 Plus 1TB M.2 PCIe 4.0 x4 (to buy unless suggested otherwise) - Fractal Design Define R5 ATX Mid Tower Case (to buy due to 8-10 3.5" HDD bays) - 2x WD Red Plus 14TB (intending to buy more) - EVGA SuperNOVA 750 GT 80+ Gold (owned) No OS selected. Have used Windows 10 extensively and very basic Ubuntu 16.04, 20.04, 22.04. Open to suggestions Hi all! I'd like to repurpose my old 5800X and RAM into a hardwired, simple NAS for backup and remote access, similar to what I'm currently doing with OneDrive. I looked into dedicated NAS' but think this will suit my needs more and for a similar price. I'd use this computer as the central storage for my Plex Media Files, so my 11th Gen Intel NUC (Beelink SEI11) can pull them over the network for ez transcoding and distribution to myself and my few dozen users. Currently have those 2 WD drives connected in a 2-bay USB 3.0 drive to great success. Additionally, I'd like to have some of that storage dedicated for myself and my family's personal files. Likely only needing 10TB for that, for now. I'd like to get more drives, potentially filling out all 10 bays with 14-20TB drives over time. I have a basic understanding of RAID, but my main goal would be to ensure all personal files and media files are backed up. Unless compelling, I don't see a need to speed up past regular HDD speeds. Among that, I'd like to experiment with Homelab stuff, but am only experienced in using Google's and TP Link's IoT ecosystem. I can look up guides for that separately. Lastly and lowest priority, I'd like to have this computer hooked up via HDMI to my living room TV for occasional games, VR to my Quest 2 via wireless (my tried and true router is in room and ready) and/or Steam Link from my personal gaming rig (hardwired to gigabit network, 7800x3D w/ 3080 10GB). I'm curious if I should explore virtualization for this, or if I could pull all this off with W10, Windows Server, a Steam friendly Linux kernel, or whatever you may think. I watched LTT's Gaming Rig & NAS video and it inspired me that this could be possible, though I may need another GPU if going the virtualization route. What do you guys think? I'm open to exploring many avenues and alternatives. I appreciate all your help!

My name is Jeremy (Yiru for most people online). I would like to get advise on the following. I want to run the following on it. SQL (with Redis as cache). Minecraft servers (I am making a little network around max 100 people so far). Virtual machines. webserver using nginx/apache2. maybe some other things in the future. 2 idea's I had so far. 1 or 2 servers. (6 cores/server minimum for 2 | 8 minimum if 1 server) using multiple blade servers in an enclosure. What I want advise on. I want advise on what the best option would be. If there are better options I also would like to know. Budget. I could spent a max of 2000 euro on it. I would like it to be not 2000 if possible. (I will keep an open mind on budget if needed) Where to buy. I live in the Netherlands. But cant seem to find good places to buy from. I would love to know if people have good links to those if possible. Software is not an issue. I already have that covered. If any questions just ask. I would love to answer them. Thanks in advance. -Jeremy (Yiru)

I'll keep it short: I am a software dev, I want to test cross-platform applications but I do not have an apple MacBook or similar. I do have a fairly adequate PC with a 256GB Sata based C drive for my main OS (W10), I also recently went out and got a 1TB NVMe (WD BLACK) for storing all my projects. I also have a 1TB 7200RPM HDD for storing data. My question is; Will setting up the vmware on the NVMe in this configuration allow me to run MacOS as smoothly as it is running off of any other MacBook? If not, what can I improve or change?

Apologies for spelling or grammar, I'm on my phone. So earlier today I fired up one of my VMs in VirtualBox. I tried to forward a USB device, which I've done before without issue, and Windows couldn't recognize it. I had the thought that maybe it's because I had upgraded from Debian 11 to 12 as the host and maybe I needed to check for updates and maybe update the extension pack that facilitates things like USB forwarding. The extension pack in the past has always been a separate download on their site, so I headed over to VirtualBox(.)org , and it seems kind of barren. The big old download button takes you to a page with links to the source code and that's about it. The download page used to be filled with links to the extension pack, binary installers for various platforms, repo instructions for various Linux distributions, etc., and literally none of that was there. The only thing that remotely looked like a link to actually download it was for "older builds" like 6.1, but when I clicked that it just took me to a page with a couple lines explaining that the extension pack was licensed a certain way with a link to the license, but no links to actually download anything. The only way I can see that you can download it from their website now is to download the source code and build it yourself. The Debian repo I already have set up appears to be working and contains a copy of 7.0, but if I want up update the extension pack, or even set it up on a different system, I'm just out. Adding a Debian repo requires importing and trusting a signing key for that repository, none of which I can find now. I can only really think of two explanations: 1) VirtualBox is a huge net loss for Oracle and they're cutting it loose. 2) Tons of companies were using the free, personal version of it for business purposes, so they're trying to corral those people into buying a support license from them and are just removing all the free downloads from their website. Update I just tried to visit their site on my phone to double check and make sure I'm not just blind before posting this, and the whole site is down now. I don't mind using Qemu on Linux, it works fine. I just kept VirtualBox around because I only occasionally use VMs for a few very specific tasks for my personal use, and it was easier to get set up with, and when reading from a passed thru optical drive it seemed to perform a little better, at least the last time I tried comparing. I had noticed though that, the last time I tried starting a Windows 10 VM in VirtualBox, if you install the guest additions, which includes a virtual display driver, it breaks the aero/transparencies in the Windows UI so that weird things happen, like the background of the start menu being completely transparent. And it has been that way for a while. Maybe they are just abandoning it altogether.

Hey there! Now, I know even Linus has already done this a long time ago, but what I need to do is perhaps a tad bit different (and everywhere I search explains what Linus did, and not what I need) See, my sister is in need of a more powerful computer than her laptop and my gaming PC should do the cut, however, I still wanna keep using it. I want to have either a virtual machine, a secondary user, or something along the lines, running in the background of my PC, and have her laptop remotely connect to it as I use my PC at the same time. I can't really do what Linus did because I don't have a second monitor to spare (for the record I do have a two monitor setup, but I'm keeping it for myself since it's a very old 4:3 monitor and my sister doesn't like it lol) and I don't got another pair of mouse and keyboard laying around, so her laptop have to be the peripherals and monitor. Is it possible? How could I achieve this? Note that I won't be doing anything power intensive so my hardware should be able to handle it. Unless it's a virtual machine, but I don't know much about that, hence why I'm asking. Help would be greatly appreciated!! Any and all solutions/responses are welcome.

PREFACE: Microsoft teams is awful, and I wish we didn't have to use it, but here we are and I need to get to the bottom of this. Everyone's pissy about teams never working for them, so they all just use the web client for the time being. However, our endgoal is to have the application working flawlessly. And due to not running a fully persistent setup, proxy settings, white/blacklists for websites, outright security policies, Azure itself, we can't figure out what the root of our problem is with so many symptoms. CURRENT ACTION: As of the moment, we have implemented a script that purges all files that are not in a folder (out of seeing errors with "desktop-config.json" "preauth.json" "settings.json" "storage.json" at multiple points in the logs) within \AppData\Roaming\Microsoft\Teams. The folder is being synced by FSLogix, our main idea being that we want the Thin Clients to store userdata and files on our servers instead. However, This event happens before the system shuts down for the night, making teams effectivley launch as if it was the first time it's launched every day. This method has solved around 80% of the cases we have experienced, preventing them before they happen. The other action we are currently taking is manually going and running a script to purge the files similar to the nightly purge. This is done system by system, user by user, and cannot continue if we want to get things done in our department. The files that are currently wiped is attached in the photo. MOVING FORWARD: I am likely not able to share log files from teams, but my list of running theories starts here from them: WAM fails to log in the user, sets "WAM fallback error" to true, and then sets itself to use ADAL, only occasionally launching the app. Not sure if this correlates specifically with our firewall, but I don't believe it's likely. The error code produced is almost always "80070003", which I have not managed to find documentation for. Note: I am obviously at my job and wouldn't be playing with software and virtualization like this otherwise. It might be a moment before I reply, and keep in mind I am not going to be able to share a good bit of information about the issue as it's not my issue to disclose the company is facing. Thank you all for any and all help in the years I have been here, active or not.

Budget (including currency): $1200 - 3500$ USD Country: Bulgaria Games, programs or workloads that it will be used for: I want to Work(programing) on MacOS and game on a Windows on single PC. I hate having to restart to switch OSs. I need good configuration to do so. Other details: There are atleast two options: Running Windows and MacOS on VM Running MacOS(Hackintosh or Native) and running games on Windows VM (Are we there yet?) I need lets say 3 variants: budget, price/performance, performance. I usually prefer second hand hardware. What is the best software solution/configuration to utilize this idea? Is there a LTT video about this?

I'm trying to set up a Hyper-V VM but if I attempt to connect the the VM is just says 'Cannot coonect to the virtual machine...' but what's interesting is the preview works fine.... I have no clue what is wrong with it. I'm running Windows 10 Enterprise LTSC 2021. Things I've tried: Disabling and Re-enabling Hyper-v (via Turn Windows Features on & off) Restarting VMMS service Checking to make the VMMS is listening on the right port (2179) Disabling NUMA spanning Creating a new VM Disabling Windows Firewall Removing vmconnect.exe from Windows Security Exploit Protection thing Adding my user to the Hyper-V Administrator group Probably something else I forgot Any more ideas?

Hello to everyone, after realising my first "server" build, i want to extent my vision. I work in a company where there are about 18 computers and i would like to centralize all of them. Basically ditch the one person-one pc tower concept and transfer all the computers into vms in servers. I started by making a custom server [5950x/64gb/2TBnvme/2x1660ti/ESXi]. This server is in a server room and holds 4 VMs, two of them are used by designers for 2D-3D CAD and the other two for office use. This system works perfect for now. So i want to use the same concept for all the other pcs in our business. All the VMs in question will only be used for office use. I am looking into making another server consisted of the following: Ryzen 5950x 64gb Ram 2TB 980 Pros 6*gt1030 ESXi 7.0 (is there a better host for this application?) After a lot of research i found that the easiest and cheapest way to access the VMs is by using a KVM extender (kvm over ethernet). That is the reason i will use the GPUs as well. My question is whether i can hook up 6 GPUs in a commercial X570 motherboard that has 6 pcie (2* x16 & 1* x8 & 3* x1) using x1 to x16 riser cards? The gpus will then connect to the KVMs and give access wherever in the network. Reasons to do it: Central management Might be cheaper on a full scale (rather than buying seperate pcs) Easy to deploy new pc Easy to backup Easy to redeploy after failure Controlled enviroment in a server room with UPS Might be used for computers hooked-up on machines, which is a big plus in case of failure. Easier to maintain with consumer parts Reasons not to do it: Big pain in the a** for the one realising it Might be more expensive to start with Don't know if it will actually work properly Feel free to leave your negative/positive comments and thoughts :)

How does QEMU perform compared to VirtualBox on macOS? On my Kubuntu gaming desktop, I use QEMU/KVM for all of my virtualization due to being able to do GPU passthrough & being generally faster than VirtualBox. I’m not that familiar with macOS as this is the first time I’ve ever used it (job requirement). My coworker/mentor recently just talked about UTM, which seems interesting and might perform better on my 2016 MacBook Pro compared to VirtualBox because it only supports macOS. Only reason I’m using VirtualBox is because I needed something quick, and I know it works (VMware isn’t free at all). Edit: adding Apple Virtualization. Just saw that when I launched UTM, and I'm not exactly sure what that is or how it compares.

Before I start, I'll just get this out of the way: I know truenas isn't very highly regarded as a hypervisor for virtualization whether it be core or scale, but hey they're trying so I figured I might as well try too. If I can't resolve this issue after this forum post, then it'll likely be over to proxmox with truenas and other vms underneath for me... Anyway, onto the issue: I'm trying to get a VM up and running but having difficulty with passing through my USB controller. I finally got it separated out to a IOMMU group where it's all alone, however I now get a new error: Error: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/middlewared/plugins/vm/supervisor/supervisor_base.py", line 165, in start if self.domain.create() < 0: File "/usr/lib/python3/dist-packages/libvirt.py", line 1353, in create raise libvirtError('virDomainCreate() failed') libvirt.libvirtError: internal error: process exited while connecting to monitor: 2022-09-04T22:23:30.894130Z qemu-system-x86_64: -device vfio-pci,host=0000:02:00.0,id=hostdev0,bus=pci.0,addr=0x7: vfio 0000:02:00.0: failed to setup container for group 2: Failed to set iommu for container: Operation not permitted During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/middlewared/main.py", line 176, in call_method result = await self.middleware._call(message['method'], serviceobj, methodobj, params, app=self) File "/usr/lib/python3/dist-packages/middlewared/main.py", line 1293, in _call return await methodobj(*prepared_call.args) File "/usr/lib/python3/dist-packages/middlewared/schema.py", line 1272, in nf return await func(*args, **kwargs) File "/usr/lib/python3/dist-packages/middlewared/schema.py", line 1140, in nf res = await f(*args, **kwargs) File "/usr/lib/python3/dist-packages/middlewared/plugins/vm/vm_lifecycle.py", line 39, in start await self.middleware.run_in_thread(self._start, vm['name']) File "/usr/lib/python3/dist-packages/middlewared/main.py", line 1208, in run_in_thread return await self.run_in_executor(self.thread_pool_executor, method, *args, **kwargs) File "/usr/lib/python3/dist-packages/middlewared/main.py", line 1205, in run_in_executor return await loop.run_in_executor(pool, functools.partial(method, *args, **kwargs)) File "/usr/lib/python3.9/concurrent/futures/thread.py", line 52, in run result = self.fn(*self.args, **self.kwargs) File "/usr/lib/python3/dist-packages/middlewared/plugins/vm/vm_supervisor.py", line 62, in _start self.vms[vm_name].start(vm_data=self._vm_from_name(vm_name)) File "/usr/lib/python3/dist-packages/middlewared/plugins/vm/supervisor/supervisor_base.py", line 174, in start raise CallError('\n'.join(errors)) middlewared.service_exception.CallError: [EFAULT] internal error: process exited while connecting to monitor: 2022-09-04T22:23:30.894130Z qemu-system-x86_64: -device vfio-pci,host=0000:02:00.0,id=hostdev0,bus=pci.0,addr=0x7: vfio 0000:02:00.0: failed to setup container for group 2: Failed to set iommu for container: Operation not permitted I have no idea what to make of it and haven't been able to resolve with any of my googling and guide reading.

My question is, is it possible to make a physical usb port entirely set to be used exclusively for a VM. I mean, you plug something in the port, it won't ever show up and be accessed on the host. I use VMware workstation and the closest behaviour i can get is simply redirect any usb device connected while a VM is running to the foreground VM. If i then close said VM, the usb device will automatically be connected to the host. If no VM is running to begin with, the usb device will connect to the host. I don't want that, i want the USB port to be accessed ONLY by a VM, not by the host, ever. I'd like a usb port on my machine to be kinda safe to plug random stuff in that could ONLY be accessed in a VM environment with no potential (or at least less) room for mistake. Stuff like a rubber ducky, random "usb drive" found on the parking lot etc. You know what i'm talking about. I can also use Hyper-V if this behaviour isn't possible on workstation but is on Hyper-V. Also, if it can be done on Proxmox i'll take the tips also for my knowledge. I guess I'd need a Type I hypervisor for that kind of stuff? Thanks!

Budget (including currency): Up to $25k Country: United States Hello I am a major PC enthusiast and do a lot of programming in crypto, 3D modeling, Game design, as well as gaming in general and in anticipation of the next gen Ryzen launch and the new rtx 4000 series I wanted to look into a endgame system to serve all my needs (and wants XD) equally. Now of course I understand this cannot be done with one system so I was initially thinking a corsair 1000D build with the ITX motherboard tray running a 16 core Ryzen chip with whatever top single GPU comes out from Nvidia and then in the main tray a thread ripper with a AMD graphics card as on this system I will be running a KDE arch Linux install and I would like to use and hopefully contribute to Wayland and Linux gaming development in the future. Now I should mention some needs from the workstation tray. I need it to be able to run a U.2 SSD array in either raid 5 or 6 (whichever you guys think is best when dealing with money) most likely virtualized under a hypervisor as a NAS and then two other VMS one for general system usage as well as pushing and compiling code (high core count necessary) and then another which is capable of allocating individual threads to run various crypto full nodes. So for example I want one full bitcoin node, avalanche, ren bridge, and lightning node, (in addition to something like a media server, PLEX perhaps running on a separate HDD array) with each of their data stored on the raid array who's processing is handled by a single dedicated thread on my CPU. Both systems should have a decent amount of ram I would like the development vm to have at least 64GB if not 128GB and the gaming to have at least 32GB. With that out of the way let me describe some problems I ran into while specking out a design. First of all consumer thread ripper is being discontinued according to Linus but some leaks have suggested it being brought back for the 7000 series in 2023 with up to 96 cores. Now this is purely speculation on what AMD might come to bear and I don't want to rely on that or wait however long it's going to take for AMD to release that chip but I am also 100% against using a Lenovo workstation. Mabey a sever motherboard with EPYC? or maybe I can gut a Threadripper Pro rig if they haven't locked down their functionality? Otherwise let me know if it would be better without thread ripper or with three Ryzen 7000 systems instead (I perhaps would like to sell some of this in the future so that could be good). My main concern there is my interlink between the systems. I want to be able to transfer files from one system to the next at speeds at least at 10gigabit or preferably 25 gigabit. And Ryzen 7000 only has 24 PCIE gen 5 lanes. With one GPU in two of the systems and perhaps a raid card in the last as well as a highspeed M.2 NVME array for the gaming and development systems I'm not sure Ill have enough lanes. There is some speculation that M.2 SSD's could be reduced to 2 lanes each which would allow me to fit 4 M.2's into the lane budget but then I would need control of lane allocation which could be done but IDK how feasible that is. I guess I perhaps don't need 4 NVME's per system maybe just two on the gaming and development motherboards but I just want to know I'm going to be able to saturate all my network bandwidth. This also opens up the problem of a new case solution maybe the corsair 1000D isn't the best. I love the idea of rackmount PC's but nobody sells them outright from what I can tell. If you have any ideas that would be greatly appreciated. Another problem is that Ryzen 7000 only supports ddr5. I'm not sure if there's anything I can do about this but currently ddr5 cas latency paired with mediocre speeds and their outrageous prices is very unappealing. Hopefully you guys think we'll see better latency and faster speeds by the time 7000 drops but without backwards compatibility for ddr4 I will be literally paying more for less because every ddr5 kit on the market is slower than a ddr5 3600 C14 kit. System latency and responsiveness is a huge thing for me I don't like clicking on applications and boxes and nothing being shown on screen. Also loading assets into memory is one of the really annoying tasks on my current rig which has very slow ram. Like I said nothing can probably be done I'm just throwing it in there. On the gaming system I like to run triple A as well as indie but were always talking demanding applications Including VR, CP2077, Call of Duty, God of War ect. Also I was wondering about monitor ideas. I love to watch high quality movies which i would stream off the plex server HDD array. I have a huge library of blurays (digitized of course) so i was hoping up to like 80TB of storage on the HDDS combined. And as for monitors I'm drooling at the idea of the new QD OLED ultrawide, but idk if its a good idea to buy the Alienware now or wait and hope for a Samsung native release in the coming months. I would also like to have displays for monitoring the NAS and Node servers that I'm running so i can keep track of their performance and uptime. And then maybe another display for development windows but with the size of QD ultrawide I'm not really sure of a good way to position these on my desk lol. Anyway use leaks speculate all you want I would just like to see what you guys come up with. The timeline on this build is for summer to winter 2022 and budget is somewhat flexible so go crazy if you need to. I just don't want to pay more for less like any other person.

So here's the deal, I have a /29 IP block from ExtraIP, and I want to assign those to my virtual machines on my server so that I can access them through (for example) 37.123.213.231 instead of my usual public IP. I have a KPN Experia Box V12 router, and I can't use that to route any IP addresses. Can anyone help me? I have virtual machines (ubuntu server) set up on my dedicated Ubuntu (GUI) server. I would like to know how to assign each of them a public IP address, since I want to start a VPS hosting business, but I don't know how to get started with the user's IP addresses. Explain to me like I'm 5 if you can, as I'm quite a noob when it comes to networking

Budget (including currency): n/a Country: BG Games, programs or workloads that it will be used for: Hopefully AAA Hello Everyone, I am looking into configuring my laptop into working with multiple OSs semi-simultaneously. What I hope to do is to run Windows and Ubuntu on a hipervisor and be able to almost instantly switch from one to the other. My plan is to virtualize both on XEN, and run the hipervisor as the main OS, switching into the OS of need. This setup will help me a bunch in work, plus I am also curious if it/how it can be done. Ideas and considerations I have so far: 1. Hipervisor needs to support release upgrades. - Ubuntu does, and CentOS doesn't. The idea behind this is that I can set up the PC once and not have to bother with it for a long time to come. Just update and reboot hipervisor every now and again. I'm not familiar with all distros and hipervisors out there, so will appreciate a good combo. 2. Hipervisor needs to support resource overselling. - OpenVZ supports it, however, it doesn't support Windows. If this is to actually be practical, being able to utilize the majority of resources of the system from both OSs is essential. - An idea to make the above happen a bit easier would be to put the OS you are leaving into sleep mode, so it can suspend it's status on the SSD and free almost all of the resources for the second OS 3. Both OSs can have their own virtual disks, but user storage is configured as a network drive towards a partition on the hipervisor OS, so either can access it 4. Linux doesn't necesarily need access to the nvidia gpu. As far as I know, the GPU can only be assigned to one OS on a hipervisor. This may turn out to be an issue, if I can't use my external monitors on Linux without the nvidia driver and just off internal graphics. Will need to look into this a bit further, not sure how my motherboard is wired. -------------------------- Benefits of this setup: 1. Hipervisor OS can be ultra secure. You can disable all external-access services like FTP,SSH, etc and just allow updates through the FW. 2. Disaster recovery would be much easier. Windows update wiped out its System32 folder? You can reinstall and be back up in minutes, and still have a working PC in the meantime. 3. System updates can be configured to run completely invisibly from the user. While in Ubuntu, Windows updates and restarts, and vice-versa. Pair that with the fact that I do tend to turn off my laptop once or twice a week, I will be always up to date and secure. 4. Since you are basically running 3 OSs with their OS encapsulated from the other, cleaning malware and viruses will be much easier. If Windows gets a virus, you can clean it with the other OS. Plus, the shared storage will be scanned by all 3 OSs, so you know that will be clean. I'm sure I'm forgetting some details, and will update this thread as the project progresses. Any ideas/advise will be appreciated. Cheers!

My friends has a computer that is running very old and crappy hardware, and it struggles to run some of the games he wants to play. I recently learned about virtual machines, and I was wondering if theoretically I could host a virtual machine on my higher end PC, and he could remotely access that and play higher end games? At that point, would a Geforce Now subscription make more sense? I just had this idea and hope someone here can tell me if it makes any sense.

Hey! Looking to build a fairly large first virtualization server (Budget of around $2000 aud or about $1500 US) for a multitude of reasons, mostly for development services for myself and some friends (Gitlab, Codeserver and Docker to deploy code, Plex + bittorrent and a Windows 10 VM and a couple more) Was looking at building a 1st gen EPYC server, but couldn't find anything great with a high clock speed + expensive components like ECC memory. So i was looking at a used 1950X Threadripper on ebay that i fit into my budget. Specs are here: (https://au.pcpartpicker.com/user/Wrecked256/saved/ZMbWt6) I haven't run a server before only some Virtualbox VMs for learning so am not familiar with resource requirement for services or a hypervisor to run it all on (was thinking Proxmox?) Any suggestions on what hardware i should consider? Noise is also a big factor as the machine will be sitting right next to me (No proper ethernet networking throughout the house) Thanks for any help!

I'm running windows 10 under qemu/kvm and I'm trying to pass through my graphics card (RTX 2060 mobile), but it always throws code 43 because the VM doesn't have a battery. I've tried the method of creating a fake one through ACPI tables but no luck. Is there any way to pass through my battery or trick windows (spesifically Nvidia drivers) into thinking the VM has a battery?

I have recently purchased a PowerEdge R430 and had a few questions. The configuration I ordered contains one e5-2630v4, but I would like to upgrade it upon arrival. I am looking at getting either another e5-2630v4 with 10 cores (bringing the server to 20 cores spread across 2 CPUs at 2.2GHz (3.1 boost). My question is: Should I just get the $120 2630v4 or should I sell the one that is in there and buy an e5-2698v4 for $400-500 with 20 cores clocked at 2.2GHz (3.6 boost)? My knowledge tells me that the singular 20 core is best, especially since I will eventually be able to upgrade to two of them (and that is what I eventually want regardless of what I do now). I also believe that it is better to have all of the cores on one CPU, since there is less performance lost when the CPUs both have to communicate between each other and the chipset. I am planning to use this server to offer up virtualized computing to customers and so I need the core count to be higher than ten. Also, if I am running something like ESXi or linux with Docker, how many system resources should I allocate to the host OS/hypervisor. I was thinking about reserving two cores and 8gb of ram, or does ESXi do this on its own and not really need dedicated processor cores to manage these instances? Edit: The server also contains 32GB of ram, I believe DDR4@2133MHz. I plan on offering package deals of 4GB of ram per server core, so I would need to upgrade to 80GB (probably going to get 96 because it is an even multiple of that 32 that is already in the system). If I run only 1 CPU, that would give me just 6 RAM slots, meaning I would have to purchase 16GB sticks, and possibly having to sell the RAM that is already in the system, since these cheap ebay listers usually just stuff these servers full of small capacity sticks. I suppose regardless I should buy higher capacity DIMMs if I am planning on eventually upgrading the server to have 40 cores with 192Gb RAM or more.

Budget (including currency): 1000 USD Country: USA Programs or workloads that it will be used for: Running latest MacOS install through Qemu. Hoping to use Xcode as well. Other details: I’m unsure if this is actually a better option performance-wise to a 1000 USD M1 MacBook. However, if they are at least somewhat comparable, I would greatly prefer a desktop PC. Potential time commitment required to optimize the VM to get good performance is not an issue. Also, is a decent GPU necessary for this kind of application?

Hi, This will be my first post in this forum. So straight to the point: I have setup my PC to use Hyper-V and have been facing a problem with networking. I have added an external virtual switch in order to access my VMs from other computers within the network. Just last night I have noticed that since setting up Hyper-V with external switch, I've been experiencing random disconnections from the internet. This was especially annoying because I noticed this while playing some Left 4 Dead with friends. To be more specific, these disconnects happen in such a manner: PC will lose connection momentarily for approximately 5-10 seconds Connection is restored for around 30 seconds PC will lose connection momentarily once again for approximately 5-10 seconds Connection will be restored again, until such disconnects happen again Out of curiosity, after that gaming session I ran a ping -t on cmd and left my PC overnight. The following morning showed that I've lost around 30 packets throughout the time the command was run. Searching through the event viewer showed me event ID 22, 24, 21 and 23 recurring overnight. I've attached the screenshot of event viewer for reference. Several solutions that I've tried consist of the following: Disabled Virtual Machine Queue for all VMs in Hyper-V Manager Updated my Realtek ethernet drivers Deleted the external switch and created a new one Restarting the PC (cuz why not) All solutions however, have been to no avail. I'm still experiencing these issues at seemingly random intervals. I've searched everywhere and I have not yet seen anyone that has experienced the exact same problem as me so I'm really getting kinda desperate here and any possible solutions are very much welcome. Here are my PC specs: Ryzen 5 3600 GTX 1660 Super Asrock B450M Steel Legend G-Skill TridentZ Neo 32GB (4X8GB) 3200 MHz Windows 10 Pro Version 21H1, Build 19043.1110 Thanks in advance!

What would you guys recommend for a GPU or GPU's in a sever. Planning on running 3-5 SolidWorks applications through virtualization as well as a few other VM's and have the server as a file server. We have good luck in our workstations with Quadro p1000 but that's for our more high end work.
