Trying to make a few different, ISOLATED, NAS on the same machine Have a Dell r320 server. 4 drives in the front connected to H310 mini HBA in IT mode, internal 2.5 ssd with OS Plan to add a JBOD / disk shelf with SAS cable to an HBA r320 has 2 pcie slots. 1 for an HBA for JBOD, second for a 4 port nic (or SFP+ 10G in future) ------- Goal: Have 2+ NAS running on the same machine, but isolated from eachother for security Each VM has its own disks and its own ethernet port and be on its own segmented network Each VM is independent and easily migrated (not using docker) Plan: Install XCP-ng hypervisor on the hardware (install on internal ssd) Create 2+ ubuntu VM's that are each on their own network (via different ports on the nic) Hardware passthrough the drives with IT mode and passthrough in XCP-ng so the VMs can only access certain drives (I believe you can do this in XCP-ng center) I have (currently) 5 isolated networks, created using pfsense running on a watchguard XTM5, I use physical separation (NOT vlan tags) and 5 separate gigabit switches Layout: 1 VM using internal H310 HBA and just the 4 10TB drives in the caddys - backup server for VMs running on the rest of my rack. Orchestra can do scheduled delta backups 1 VM for files share server using pcie HBA and connected JBOD - network accessible file share using samba (potential) 1 VM for jellyfin media server, running on JBOD - host VM will live on another hardware but just network attach this storage (optional) 1 VM for ISO library for creating other VMs with - samba share - live on management network Software: I plan on using some sort of software raid/ file system running on ubuntu, but have not figured out what yet leaning toward ZFS or trueNAS core or scale, maybe snapRAID. Each has downsides, still researching Unraid probably off the table since i want to have multiple installs, and unraid spendy and has its own downsides ------- This setup will not be used for running applications or services, just as network attached storage I have plenty of other compute servers that run everything I need ------- Thoughts? Feedback? Better ideas? I am trying to figure out as much as i can ahead of time Thanks! :]

Hi! I'm trying to connect to a virtual machine running on a remote PC. I set up wireguard VPN in hopes of it just working, but it does not. Any ideas on how to get this working?

I'm new to VMs so apologies if this is a stupid question. I want to run a windows 10 VM on a separate keyboard, mouse and monitor. I want it to essentially be a separate computer which my little brother can game on while I get through assignments cause I'm reluctant to go to the library during a pandemic.. It's a beefy PC so it should be able to handle a windows 10 VM running the games he wants to play while I do my work. Just wondering if it's possible and how I do it.

Hello guys. I have to install ns3 on an ubuntu vm for a lab on my uni. https://www.nsnam.org/wiki/Installation#Installation There are the steps for an ubuntu system. I did them and i jumped to installation like the steps said. After i typed git clone https://gitlab.com/nsnam/ns-3-allinone.git i saw what you see on the photo ( sorry i couldnt prnt scrn on vm ). I couldnt find any more info for this error and im new on ubuntu and i cant figure it out. Have you got any ideas?

Hey everyone! After much headache with iommu groups, greedy Nvidia drivers not letting go of my secondary gpu, and finding a qemu configuration that actually boots, I'm completely stumped with getting out of this EFI shell using qemu. No matter which firmware I choose, aside from bios of course, which just hangs haha, I can't seem to get the windows install DVD to boot. I've tried going through the shell manually, selecting the FS1, and trying all of the .EFI files, after which I'm told to press any key to boot DVD, at which point I'm just hanging at a splash screen. Anyone have experience with this? I was inspired by Linus's build running all the PCs in his home, doing a little preliminary run with just one vm to figure things out.

So i have a vm in azure and i was wondering how i can use my microphone on it because idk what to do thanks:)

So I'm planning to buy a 3900X along with UNRAID but I'm not sure if I'll have enough PCI Lanes. (If so please give me recommendations for another CPU if so) GTX 1080 for one Gaming VM RTX 2060/70 for the other VM NVIDIA P2000 (or higher) for Plex Transcoding 5 x 8TB SATA Storage (maybe 4 drives instead idk yet) 1TB NVME M.2 2 USB Controllers or if the Motherboard has enough USB IOMMU Groups I think that's about it The 3900x has 24 lanes, 4 for the chipset though, so 20 usable (This is Gen 4 PCI btw, so i might be able to get away with things in 8x instead, and idk how much the P2000 needs for Plex Transcoding) I can make compromises too

I am looking for a mSATA SSD with DRAM, something with a strong QD32 performance. Since I am planning to run VMs on the mSata SSD, I assume I need QD32 and not just QD1 only. Any suggestions? I am willing to go brandless names but with those SSDs, I don't know if they have any DRAM onboard.

Hello, I have been stuck for more than a week on a problem. I have a debian vm in my server which will serve as a router and I seek to redirect the traffic of my container and other vm in this vm but after doing research and posting messages on forums I did not find any solution. I may have had a clue about using vlan but nothing more I hope someone can help me. thank you in advance for your help, James.

So I read an old forum post about running .exe files on Linux is way faster (and cut rendering speeds by half) , and I also read another forum post about how using VMs are really heavy for your system, so I wanted to try out Cinema 4D for Ubuntu 20. Any Tech Savvies in here who knows any exe launchers or light VMs for my old busted laptop?

So on my pc I want to run a vm with linux on it but the base os for my system is windows. What requirements are needed for a fully functioning pc and vm?

I have a server which I would like to use to serve as both a NAS and hypervisor. But I have not yet been able to find a suitable configuration and/or software. Maybe anyone here can help. My goals: - Manage VM's via a GUI, where the ability to easily clone VM's is a must. Support for VM templates and snapshots would be a big plus. - Create network shares via a GUI on a mirrored array. Reliable storage is a must. Support for snapshots would be a big plus. Options I have tried so far: - Unraid: Easy to use, but limited VM support. No GUI support for cloning. - FreeNAS: ZFS support and out-of-the-box support for ZFS snapshots. VM support seems really minimal. - Proxmox: Excellent VM support, but no support for creating network shares. FreeNAS as a VM would theoretically be an option, but I do not feel comfortable by having a hypervisor between FreeNAS and my data. Do any of you have any suggestions on how I can best achieve my goals with a single server?

The problem is the next 1 gaming PC 1 Tv they are too far from each but in the same house I want to play on my tv without moving the pc from where it is my internet connection isn´t too good for using cloud streaming and barely enough for Lan streaming, also due to the quarantine I can´t buy stuff I tried to install retropie with parsec, which was not so good due to commands and problems installing packages. but that does not matter since using parsec between 2 PC's with Windows 10 shows that the quality was not good. Then, I tried steam link and moonlight + Nvidia experience stream to take full advantage of the Lan connection capacity, the results were decent but with quality problems due to the low bit rate due to my internet connection. I remembered that I had an l300 NComputing, perfect because it did not need much connection, it worked for Lan, I could create a user to protect my information and many advantages. the problem is that I create these devices and for the most part the virtual machines do not share the video card, so there would be no joke. my question is: Do these drives share GPUs or could they? Any idea to be able to play on my tv without dying trying?

I'm having issues trying to get emulation running on Android Studio and I was hoping someone has an idea on how to get it working? I recently rebuilt my PC going from I7-6850k to AMD 3900X with new Mobo and faster RAM. Prior to the rebuild I had it working with no problem, so I don't know if it's a compatibility issue with the Intel Software on AMD, but from what I've researched I can see other people are able to use it, so I must be missing a step somewhere? The error I get on trying to install is: If I try to run the installer directly I get a similar error message: I can confirm that Virtualisation is working as I use VirtualBox a lot. Confirmed in Task Manager: I've confirmed that HyperVisor is unavailable in Windows Features and HyperVisor Plaftorm is enabled (apparently it needs that to run the emulation) I also confirmed that Windows Defender Core Isolation is disabled (as it uses Hyper-V to perform it's task) But I'm stuck. I can't see what else I need to enable to get it working and without the emulation running I can't check what I'm doing *sad beeps*

Probably shouldn't have listed this under graphics cards topic.... I posted this in r/VFIO without much luck, hopefully someone here can help: I'm very new to KVM stuff but I already did a fair lot of research and I need some help. While researching I found this post: https://www.reddit.com/r/VFIO/comments/amvcm2/gpu_passthrough_with_an_exmining_card/ 7 And found in the replies: „It looks to me like the inf hacking done by LTT was simply to map PCI device IDs to different driver sections (ie. fooling the driver to handle a P106-100 the same as it would a GTX1060), but with a VM we can simply change the device ID (ex. x-pci-device-id=0x1c03). You'd also need to find a compatible ROM for the VM or hack your own to change the device ID and checksum, but you'd only need to do this once versus hacking every new NVIDIA driver. Of course you still have a card with no video output and I don't know if the drivers will let you create a headless desktop to use with Looking Glass or if you need a companion graphics that supports rendering into the frame buffer.“ That is EXACTLY what I wanted to do. Except I have a P104 mining card (GTX 1070 GDDR5X version equivalent) which HAS VIDEO OUTPUTS. The card is very specific, because it's severely limited by it's VBIOS. The card in fact has PCIe 3.0 x16 support and 8GB of VRAM but it has been limited by VBIOS to 1.1 x4 and 4GB of VRAM. Also the video outputs don't work (their hardware does, but they simply don't output anything because the whole display engine is disabled in VBIOS). I tried hardware flashing it but then I couldn't get windows and drivers to cooperate because they still thought it's a P104 because the device ID is not tied to the BIOS but rather to the hardware. I've done my best to hardware hack this gpu into a 1070 but then I discovered that since Maxwell the GPU Device ID is tied to the GPU die and cannot be physically modified in any way. So my last resort was obviously hacking outdated drivers in Windows but I found that incredibly impractical and unstable. Then I found that you can just pass it through to a VM and set the main OS to report a different ID to it, thus making the VM think it's a different GPU. And so started my long research... I found a very nicely explained guide for begginers: https://mathiashueber.com/windows-virtual-machine-gpu-passthrough-ubuntu/ that I am willing to use (please tell me if it's wrong before I invest countless hours troubleshooting something that's outdated or straight-up wrong). I found that an option called x-pci-device-id exists that can do exactly what I want (even u/aw___ said that in his reply and if I understood correctly he is one of the devs) but I didn't find any clear explanation where to put it in the XML config (if at all, I also didn't find which file to edit in the first place) and with what syntax. Here it is stated in the replies that option is just an experimental feature and that you need to do something different to make it work: https://www.reddit.com/r/VFIO/comments/d6cmes/possible_to_spoof_pciid_of_device_passed_through/ So of course all that left me confused and I need help: Which linux distro do you recommend for this? Please give a quick read to the guide and tell me if something significant (or notable) has changed since then (or is wrong) or link to a known good (and hopefully simple) guide? Any help is appreciated! Does x-pci-device-id still exist in QEMU and how does it work (also is it placed in the XML config file and if so where in the config is it put)? What's the difference between the regula pci-device-id/vendor-id and pci-SUB-device-id/vendor-id? Again, I am a noob, please be exact with your answers, as if you are explaining to a child (maybe not that much, but you get the point). Forgive me if I took too much of your time

On my pc (Win10) I have a hyper-v vm running which is also on Win10. When it is running using an external switch, it causes my PC to blue screen. Sometimes it can go all day without a crash but other times it could crash multiple times in a row. The blue screens only seem to occur when the vm is running using an external switch, but doesnt happen as often with an internal switch. The external switch is shared with the host OS. Using blue screen viewer, it has indicated these as issues: hal.dll NNSPRV.sys ntoskrnl.exe These have shown for the last 3 blue screens. Occasionally vmswitch.sys is indicated as the issue. I have updated my network drivers to the latest version I could find and that didn't work, I have also updated to the latest BIOS version which hasn't helped either. I use the vm for Plex related applications and use the PC for working/gaming. Any support would be greatly appreciated as this is one major headache for me!

So I have a fairly old Intel SSD that I'm trying to host some Hyper-V VMs with. The trouble I'm having is that the performance is terrible for some reason. Run crystal disk mark and the numbers look normal, but try to install a Debian VM and the utilization hits 100% and the writes slow to a couple MB/s at best. I checked the SSD over with Intel's utility, no issues found and reportedly plenty of life left. Did a firmware update, no change in the issue. Do the same thing on a Kingston A400 and it works as you'd expect a SSD to. Snappy and fast. Even my SanDisk boot drive kicks its butt (which scored way lower random reads and writes in diskmark). I'm very perplexed as to what's going on here. Any suggestions on how to troubleshoot this?

Looking to build a NAS? Want enterprise grade RAID solution for your precious data? Looking to get into Virtualization and the wonderful world of Docker? Here's my sales pitch: I can highly recommend FreeNAS Corral. There's quite a lot of info on how to get started, but I thought it might be useful to share some tutorials i've done to help get people started: I've done tutorials on: Corral + Docker https://forums.freenas.org/index.php?threads/docker-tutorial.52017/ Corral + Docker + PLEX https://forums.freenas.org/index.php?threads/freenas-corral-docker-plex-container-howto.51780/unread Corral + Docker + Crashplan https://forums.freenas.org/index.php?threads/freenas-corral-crashplan-docker-container-howto.51778/ Corral + Windows 10 VM https://forums.freenas.org/index.php?threads/windows-10-in-a-freenas-bhyve-vm-howto.51896/ If you want to use Docker and VMs make sure your hardware supports VT-x (if you're on the blue team) OR AMD-v (if you're on the red team) Good luck!

Hello, in our School the upcoming class will get Microsoft Surfaces to work with in classes.I have been asked to search for possible ways to make a exam safe environment, the Surface should have everything unlocked unless you are booting into exam mode. In exam mode it should boot an Image from an USB device and only files from the USB device should be accessible(no access to any files or other partitions).This could be achieved with a VM but the problem is that a VM can easily be minimized to access your data, so i need some kind of a bootable solution. I have thought of UnRaid for this but it seems a bit hard to configure it this way for all the students, but this is the only VM solution that came to my mind that you can´t tap out of. And of course it would be better if it uses freeware. Do you know anything that can achieve this? It would also be ok if you had a VM in Windows as long as it is obvious that someone tried to cheat (detecting if the VM is minimized). Thank you for your help

Is it possible to run a virtual machine on top of a Linux cluster so the vm has all the CPU power and resources of all the machines attached to the cluster? Or something along these lines

So I'm making this topic because I heard @Slick wants to switch to Linux as his primary OS and use Windows only for games and other things that don't work well on Linux. I decided to do the same thing right after the Windows 10 launch late 2015, early 2016. I was mostly inspired by Linus' 7 Gamers, 1 CPU video. However, I didn't want to use something like Unraid for a simple home PC, so I looked around and found out I could just do it on any normal Linux distribution through KVM. What you are going to need: A CPU with IOMMU (Intel VT-d, AMD-Vi) 2xGPUs (1 of them can be an iGPU), 1 for the host Linux OS and 1 for Windows VM Any modern Linux distribution with proprietary drivers, preferably something based on Debian, Arch or Fedora. Virt-manager Time to fiddle around with it. Optional: Synergy 2xMonitors A second keyboard/mouse to setup everything easily, which will be replaced by Synergy. I've been using it for quite some time now and it's working pretty good. At first I was using an nVidia GTX 580 for my VM but it died on me recently, so I switched to a temporary RX 460 until I can get my hands on a more powerful GPU. For the Linux host I am using a GTX 260, not a very good choice since it is not supported by modern nVidia drivers. I'm running any game that works on Linux, through Steam and I just boot up the Windows VM to run everything else. You can even stream the Windows only games on the Linux host through Steam, but I don't know how well that will work with FPS, Online games and such. For the VM, I was originally using Windows 10 LTSB N, but after switching to RX 460 I've had driver issues with Windows 10 so I switched back to Windows 8.1. You can find a very good tutorial(for Arch and Debian distros) here, although half of the stuff explained there can be done through Virt-manager instead, which makes it much easier. I can also write a small tutorial if people want it.

Hey guys, Every day it seems something new comes out about the Ryzen and people freaking out. So my question is for the guys who already got one and have hopefully done some of this work on it. I'm looking at going to the 1700 and doing a 2 gamers 1 CPU setup, each getting 8 Threads, dedicated GPU and 8GB each would be enough for me for now. My Question is has anyone tested the Ryzen virtual PC capabilities yet ? its between this or a second hand X99 setup with a i7-5xxx 6core Personally I'd rather have the brand new Ryzen but just wanted to find out what the latest word was

Just bought a TP-Link n900 model no. TL-WDN4800 wireless card. I installed it and run windows 10 on my computer and it works fine. I have kali linux running as a virtual machine in virtual box and the terminal command 'iwconfig' cannot find my wireless card. Can anyone help me solve this or do I need to go buy a USB wireless card and enable that device in virtual machine options? MoBO: MSI Z270 carbon pro CPU: Intel Core i5-7600K Kaby Lake Processor 3.8GHz 8.0GT/s 6MB LGA 1151 CPU w/o Fan, Retail GPU: GIGABYTE GeForce GTX 1070 DirectX 12 GV-N1070WF2OC-8GD 8G... mem: G.SKILL Ripjaws V Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3200 (PC4 25600) Intel Z170 Platform Desktop Memory Model F4-3200C16D-16GVRB

Hi, so I have an idea to combine my unraid server (here) which runs 24/7 hosting plex +a file server +a mint vm, and my windows 10 gaming machine (here) and selling off my old hardware. My primary hope is to lower my overall power consumption and hopefully save a little desk space. The hardware I had in mind to start with would be an asrock ep2c602 mobo, dual xeon e5 2670 and 32gb of ram (maybe eventually 64 if I need it), the gtx 1080 I already have, all the storage I have between the 2 machines, probably a new psu 800-1000w as my current psu is getting older, and reusing the case that houses my unraid server as it should work just fine. As far as vm hardware setup the thought was I could allocate 4-8 physical cores and 16gb of ram to my windows 10 daily driver, 2 cores and 4gb of ram to my mint vm, and let whatever dockers I have handle the rest. While the mobo would be expensive the processors and ram are going for cheap if bought used or refurbished. I mostly game and do light video editing on my windows machine. I would like to keep my budget as low as possible only buying parts I can't reuse. Anywho...would combining my systems in such a manner as this lower my power consumption, and would switching from a dedicated system to a vm noticeably lessen gaming performance? Thanks! -Andrew
