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?

After many years of using VMWare Workstation (currently v 15.5.6) to create and use DotNet (Visual studio, SQL, IIS) Development Environments, and trying to follow best practices, I'm finally looking for the right settings (Swap, disks, etc) to give me a development machine that is as responsive and efficient as possible. Best practices seem to vary by source, so I thought I'd expand my search into the userbase. My host is running Linux Mint 19.3 Cinnamon (soon to be 20) Intel i4790K running at 4GHz 32 GB Ram SSD for root and /home filesystems 8Gb Swap also on SSD, typically about 500M in use when VMs running Development Guest (May be 1 or possibly 2 running at a time in virtual network): Windows 10 , configured with 2 Processors 4GB memory, and single virtual disk per VM settings. So, my question is what configurations others might recommend to make the Guest feel as much like pure iron as possible, without killing the Host for other things.

So I have a workstation with GTX 1080 Ti, Threadripper 1950X, 32 GB RAM and 1TB Nvme SSD running Windows 10. I want to stream games from this workstation to my laptop connected to the local network. I can do this with Steam In home streaming or Rainway. But the problem is this makes the workstation useless as it runs the game on the monitor and cannot be used for any other work. Is there a way to stream games in the background or without displaying game and audio to the monitor so that someone else can use the worksation at the same time to do some browsing or maybe watch a movie?

I believe this may be my fault for not having a setting on or something... When playing in a game, my Ryzen 7 2700X is boosting to 4.2Ghz just fine, but the game is running the CPU0 at roughly 83% but CPU1 through CPU15 are running around 1-5%. Is anyone else having this issue? I believe I have virtualization turned on correctly in the BIOS but I may be wrong. Any help would be appreciated. Although this issue is happening with my CPU, I am still able to run the game at about medium settings with a GTX 980ti at around 30-40fps! Specs: Ryzen 7 2700X GTX 980Ti 16Gb G.

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. The system I'm on is an old Dell T7400 (Xeon E5430) that should be fully capable of virtualization, and I've made sure to enable all of the virtualization features in the bios. Running TrueNAS-SCALE-22.02.3 As always, I'm sure I've left things out so let me know if there are any other specs or info you'd like me to get. Thanks in advance to any of you kind folk that may help out

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!

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): 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.

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?

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?

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.

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 :)

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.

Hi! Decided to create an account and ask here, seeing as LTT semi-routinely makes videos regarding virtualization and multiple workstations per computer. I'll lay out what I'm looking for, and hopefully we can find a cool solution! The gist is, I want to have a single machine that resides at my home that I can use to play games on Windows while not working, develop on some Linux distro for work, and remote into when working not from home (not applicable now, obviously, but I can dream...). I have a good idea of what I'm looking for in general from a hardware perspective, but I'm looking for advice on how to configure the system. The questions currently floating around in my head are: 1. Should both operating systems run on bare metal, or should I virtualize one inside the other (or maybe both?). a. I lean towards virtualizing one inside the other, that way I only need to worry about remote access into one - in this case, which is better to run on bare metal? 2. What is the best way to remote into a machine? I saw their recent video on Parsec - is that the best solution, or are their others? 3. Are there better solutions that I'm missing for the goals I am trying to achieve (having a single 'computer' that I can access via a laptop or desktop environment)? For example, in a world where laptops were as powerful as desktops, I would be happy having a one-cable dock at home that converted it to a desktop experience (keyboard, monitor, mouse, etc) and using that laptop at work. Here's that recommended list of points: Budget & Location I am flexible on budget, but I intend to be frugal where it makes sense. Looking to get a high-end RTX card, a high core-count Ryzen 3 chip and ample RAM to handle running both systems potentially simultaneously. Located in the US. Aim The system will be used for general use and gaming on Windows, and software development in Linux. I'll want to be running challenging games on Windows (AAA, high refresh rate) as well as general productivity and light audio production work. On Linux, I'd love to compile faster than I can on my current machine (i7-9750H, 64gb ram laptop) and be able to run our full software stack locally (should be good with anything more than 32gb of RAM by my experience). I'd like to be able to remote into the machine and use it with relatively low latency (Should be easy, given that the ping between home and office is pretty low). Monitors I plan on running either two 1440p monitors, or a comparable singe ultra-wide. Are there limitations here for remote desktop (i.e. would a 1080p monitor limit my remote machine to a 1080p stream)? Peripherals Don't need any peripherals, currently happy with everything I have. And I have existing Windows keys. However, I figure this section best describes where I would ask for recommendations on software and solutions for both 1) running multiple operating systems and 2) remoting into my machine. Why are you upgrading? I'm due a laptop upgrade at work and want to take one of those slim lightweight computers those marketing guys are always toting around. Thanks for the help guys, I'm excited to see what you can come up with! Let me know if there's anything that needs clarification. - chanolluim Bonus Points: Looking to get back into music production in Logic Pro using a friends old Mac Mini - How could that fit into this situation better than just using a KVM switch between the combination machine and the Mac?

Hi! I'm looking for a preferably free Virtualization software that would allow two users to use the same computer at the same time. This computer has two monitors connected to single graphics card. I can easily connect second keyboard and mouse to it. So I'm looking for a Virtualization software that would allow setting up 2 desktops where first desktop would be displayed on first monitor and receive inputs from first keyboard and mouse and second desktop would be displayed on second monitor and receive input from second keyboard and mouse. Also being able to play sound from each desktop to separate sound output would also be needed. The said computer does have 5.1 sound card available. In short I would like to allow two kinds to be doing online education on the same computer at the same time, which basically means watching two online presentations on separate desktops with separate sound outputs (two headphones). I know that in WMware Workstation Pro I could set so that guest system is receiving input from second keyboard and mouse. In fact the guest system is the only one that see the second keyboard and mouse connected. But I haven't figured out how to output the sound from guest system to for instance back-out output on the sound card instead of mixing it with the sound of host computer on default font-out line. Also I'm not doing this for myself but for my friend who does not have licence to WMware Workstation and from what I have read on internet WMware player does not support catching the input from second keyboard and mouse only as WMware workstation can.

I want to put together a NAS/server for my home but could use some guidance on what to do. I am an experienced gaming system builder but I have never done anything like this specifically, hence the help request! I am NOT looking for exact parts unless there's something critical that I overlook, just some general guidance! Here's a tentative list (No case selected yet): https://pcpartpicker.com/list/BpbwK4 I have selected the 2700X because my local Microcenter is selling them for $150 and that seems to be the cheapest way to get 8 cores. With that out of the way, here we go! What I want it to do: Be a NAS with some redundancy - I want a capacity of around 8-10TB. I do also want some speed, not entirely like a solid-state server but I do need to be able to write video to it directly in real-time - I want to be able to record my game streams directly to it, as well as use it as a DVR for my security cameras. Streams will be in 1080P and cameras in 720P/1080p depending on the camera. I am thinking of two HDDs with an SSD cache. I want to redeploy my home DNS server, my PLEX server, and my UniFi controller to it as well. Currently for some I use separate Raspberry Pis, and my PLEX just runs on my computer. I would think this could be done with virtualization but I am entirely new to building a machine with virtualization in mind. Questions: This will likely inform many other decisions: What virtualization software should I use? Since I am not experienced in this area, I would be happy with any good resources (youtube videos, etc.) as well as direct answers to questions. I am using this project to learn as much as to solve my own problem! I have investigated FreeNAS a little but it seems to not really be good for virtualization. I have heard a lot about Unraid, and it seems to be able to run as a hypervisor as well as handle my RAID setup in software rather than hardware, giving me more flexibility. Any other suggestions? I also realize that my RAID Setup will influence how much storage I can have with a given drive setup. Ideally, I'd like to be able to lose one drive and still not lose any data. If this can be done with 2x8tb drives (mirrored)or something like 3x6tb with some other configuration, I'd love to know. Drives are the most expensive part and I don't want to skimp, but want to save as much as I can. Do I need a separate drive for all my "needs?" e.g., a drive for the hypervisor, my RAID array, and another separate drive for my UniFi controller, PLEX server and DNS server? OR can I accomplish all of this with partitioning? What should be my target for RAM and CPU cores? How many cores should I be dedicating to my hypervisor vs. NAS? I know what I need for my DNS and controller but the rest of the stuff I am not very familiar with. Again, I believe a lot of this will be influenced by the virtualization software choice. Should I invest in an extra hardware NIC for a separate physical management interface? Anything else I am missing? Thank you in advance for all of your help!

I have been trying to follow Linus's video on creating a MacOS VM using QEMU, however I am trying to do it on Windows. I am using this post and this repository (different from the one linked in the article, but is almost the same in terms of functionality), as the one linked in the description was outdated. I have an AMD 3900X with a NVIDIA RTX 2080 SUPER as my main GPU and a RX 580 as my MacOS GPU, all running on Windows 10 Pro. I have enabled Hyper-V and all of its associated features, and it works fine, but QEMU doesn't. I have had to modify the commands given in the repository a bit to work with Windows.

Hello friends, I think it goes without saying Zoom is one of the most sketchiest conference programs being used today, And as I have a job interview this Friday, I would like to get it running in a VM first. I've tried pushing my camera both with the Virtualbox extension pack and as a standard USB device, neither work on Windows or Linux (Not pictured because my PC BSOD when I kill the VM but I also tried Manjaro), Camera is a C920 Pro, Works fine on my base system, Any feedback would be greatly appreciated!

Hi LTT community, I am looking at creating a single machine to serve as a both a server (for media (plex), and package manager server) and a normal desktop workstation (mainly used for software development). So here are some more details... Motivation / Background: I currently have a desktop (4790K, GTX970, 16GB DDR3) which is great but I would really love more cores for building. I am a software engineer, and I often build gcc/clang and other big projects where multi-core scaling is utilized extremely well. So I have been wanting to upgrade to an at least 8c/12t cpu, above 16c/32t would be overkill for my work though. So I could just upgrade my desktop and be done with it .. but I have recently also started a plex server on my desktop, which is great but it means I have to boot up my desktop top in the other room whenever I want to watch plex on the TV. I would leave my desktop on, but I am at work (when there isn't a pandemic) for most hours of the day and don't want it sitting there being power hungry for 90% of the day (including night time of course). So I am really looking for a solution where I can upgrade my desktop to have more cores, and have some abstract machine (virtual or physical) which is running 24/7 as a server. So I could upgrade my desktop AND buy a separate NAS (QNAP or DIY, not important) .. or I could think of a much cooler / complex over the top solution which would be an awesome project / setup and see if the LTT community shuns or redeems my idea. The Plan: Have one beastly machine, 16c/32t at least 32GB RAM, with virtual environments for a server and workstation. With a single thunderbolt interface from the server to my desk where the peripherals will connect. Ideally I'd like to have this off in another room but I don't have the space. (Yes this is a little inspired from Linus' gaming server / remote peripherals setup). So I was thinking of getting an AMD 3950X (16 cores, I can dedicate at least 12 to my workstation), at least 32GB of RAM (maybe 64), keep my current graphics card (I'm not a big gamer, don't need the upgrade), and I would need help knowing what motherboard I would need to best support thunderbolt-ness. Also what type of power supply I should look into? Should I get a server-style case which supports redundant power supplies, or should I just get a UPS. I hope my plan makes sense, I would really like if anyone could give me any past experiences on if this is a stupid idea and I should just get a simple low powered NAS; is this setup even via-able? would it draw a lot of power in idle? what are some possible downfalls I might run into? (e.g. I have heard plex doesn't like hardware acceleration with containers / virtual environments). Also how server oriented should I go with this, server rack-styled case / ECC memory (I don't think it's necessary...). Notes: when I say "virtual environment" I mean anything from unraid to docker to whatever, I haven't done this before so if anyone has a good guide on what to read/use for this setup that would be great. I use linux (20.04) for both server and workstation at the moment. I have never used thunderbolt before (with a desktop), would appreciate any information on what's required here. I don't have any need for Plex remote, it's only local use and it's only every one streamer at once. (I could see a future where there is 2, but unlikely). So the plex server doesn't need too much horsepower. Thank you to anyone who actually read all this, and great thanks to anyone who end's up replying!

Budget (including currency): $350-400 US dollars Country: 00901 Puerto Rico. I got Amazon Prime. Games, programs or workloads that it will be used for: Ubuntu 18 or 20 LTS support Virtualization with a Ubuntu LTS or Linux HOST OS. QEMU, Virtualbox and VMWare Player. (I got Linux experience) Android Studio System development. (C, C++ and Rust) Web browsing 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): I'm upgrading from an Late 2016 Acer Swift 3 laptop sf314-51: mobile Intel Core i5 with 8GB of Ram and SATA 256 GB SSD storage, integrated graphics. With this machine 8GB of RAM is my problem. I'll buy in two weeks. May 18, 2020. I'll continue to use my laptop for non Virtualization purposes. I already got: 2.5 128 GB SATA SDD. Thats all the storage I'll need for now. Keyboard Mouse 21:9 1080p LG 25UM58-P HDMI Monitor Headphones Prefer: Basic or integrated graphics, enough for a Gnome GUI and Video reproduction. Future GPU upgrade VT-x/AMD-V and VT-d. At least 1 SATA removable storage bay. At least 2 SATA drive bays 60 Hz Run at least 2 1GB RAM GUEST CLI Linux OS concurrently with the HOST OS. Not all the time, only as needed. 16 GB RAM Note: I dont intend this build as a server. I'll only use it when I work on it. I'll only start GUEST OSs when needed.

I'm planing to do a lot of virtualization in the coming months for some school and tutoring projects. Since I plan to run multiple virtual machines on my computer I was planning on upgrading my equipment. First off I plan on upgrading my ram to 64 gigs but when I decided to upgrade my CPU I was at a loss. Do I upgrade from my i5 -2500k quad core processor 3.3 Ghz to an i7 and if I upgrade to an i7 is it best to buy one with more cores or a higher clock speed? Any advice would be much appreciated. Edit: Rip Title lol

Hey guys,I don't know what would be the appropriate forum for this post so I selected off-topic So lately I came across Virtualization (I wasn't aware about it at all) and I kinda liked the whole idea of emulating a whole OS on a Linux based PC. I wanted to run the Mac OS X on my PC and it turns out AMD FX processors are not supported by VMware or oracles virtual box.I mean I couldn't find a proper tutorial on how to Virtualize OS X on an AMD FX processor. The tutorials I tried weren't of any help cause the boot image was optimized only for Intel processors... and my VM would always crash while booting up the os. So if anyone of you guys know about how to Virtualize OS X (El Capitan or Seirra) on AMD FX processors,please let me know I will really appreciate your help Btw I am on FX 8320 black edition (just Incase info was needed)

Hi I have an idea for a new rig that should work fine on Intel chips but the big question is could this work on a Ryzen platform (and be cheaper). My idea is to build a multi purpose machine that runs a hypervisor (KVM/VMware) and provides separate virtual machines for Firewall (Pfsense), NAS(OpenSuSE or other distro) and Windows (Working + Gaming). To improve performance I want to use PCIe-pass trough on the graphics card (for the windows machine) and for a 4 port gigabit card for the Firewall (for the local LAN). On an Intel based platform this is "relatively easy" and supported, the hardware must support VT-d and VT-x etc. The thing though is that Ryzen offers more Cores for the same price witch is interesting for the setup I have in mind. Keep in mind that i don't require a top notch system for gaming, i play mainly older titles. My questions therefore to anyone who might have an idea are: -How well does Ryzen handle virtualization and PCIe-passthrough, does it work at all? -GPU: Nvidia or AMD (what is better supported)? Thanks for any advice.

Hi All! This is my first time posting here but I was hoping someone out there would have some information on the issue I am having. I have a custom built gaming desktop with the following hardware: ASUS Z170I PRO GAMING LGA 1151 Intel Z170 HDMI SATA 6Gb/s USB 3.1 USB 3.0 Mini ITX Intel Motherboard ZOTAC GeForce GTX 1080 FE DirectX 12 ZT-P10800A-10P 8GB 256-Bit GDDR5X PCI Express 3.0 HDCP Ready SLI Support ... Intel Core i7-6700K Skylake Quad-Core 4.0 GHz LGA 1151 91W BX80662I76700K Desktop Processor Intel HD Graphics ... G.SKILL Ripjaws 4 Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3000 (PC4 24000) Intel X99 Platform Extreme ... Crucial MX300 2.5" 525GB SATA III 3-D Vertical Internal Solid State Drive (SSD) CT525MX300SSD1 CORSAIR CS-M Series CS550M 550W 80 PLUS GOLD Active PFC Haswell Ready ATX12V & EPS12V Modular Power Supply My goal is to enable virtualization on my MOBO for the purpose of running Hyper-V. I would build my computer with a clean install of Windows 10, do all Windows Updates, update all the drivers for the GTX 1080. And when I run the HTC VIVE setup, I would get a BSOD during the setup (specifically when the drivers for the Head Gear itself is installing) OR I would get a BSOD the next time I reboot/boot my computer. The BSOD does not give an error code or stop code, just a sad face. It would then prompt me to "Restore" to an earlier point. This will work 50% of the time and when it restores to an earlier point, it would be a point before Steam VR is installed. Other times it would loop in diagnosing the error and not being able to resolve it. When this happens, I cannot boot into safe mode, cannot do a repair, and cannot recover from this. It would loop in a BSOD and have no actual stop code or error code. When viewing the event log, the error I get is error 0x0 "your computer unexpectedly shut down due to a crash, power loss, or error" ***paraphrasing*** My computer works fine if I have virtualization enable on the MOBO and running Hyper-V with multiple VMs My computer works fine if I do not have virtualization enabled on the MOBO and running my HTC VIVE VR system There always seems to be an issue if I have both configured at the same time. Any advice would be greatly appreciated!!
