And are both of your VMs experiencing this same issue with each GPU? If you're having bad performance in Windows outside of games as well, this is unlikely a bug with GPU pass through, but rather, something amiss with CPU virtualization/pinning. Can you confirm both of those Windows VMs you have experience the same issue and that the issue persists even with only one VM running at a time?

Please show screenshot of the actual errors you are seeing when trying to install an OS in a VM. The errors in libvirt are not "errors" but just notices that are completely expected.

@nickp85 and @JesterEE please attach your system diagnostics when you have a moment so I can review those. Again, I have been unable to recreate the issue in the lab, so we're going to need more help from you guys to figure out what's going on.

Please attach your system diagnostics.

Hi there, For those having this issue, please report back with a copy of your system diagnostics, and any relevant A/B testing you've done comparing 6.9-series VM performance to 6.10. For game-specific testing, please list the games you've tried. We're actively trying to recreate these issues in the lab, but so far, no dice.

Hi there, I've been trying to recreate these reported performance issues, but in my own testing, I'm not able to. Can you confirm this performance drop is occurring with other games as well or just Cyberpunk?

Hi there, One issue could be that if you're loading the GPU driver to use the GPU with a Docker container, then you can't also use that GPU with a virtual machine. GPUs need to have their driver stubbed in order to be used in a VM. When you use the NVIDIA plugin, it installs the driver for the card which prevents you from using it in a VM. This is not a bug.

Hi there, A few things to keep in mind. First and foremost is that AMD GPUs are notoriously more difficult to pass through to VMs than NVIDIA, so keep that in the back of your mind. The second thing worth noting is that the host OS needs a GPU and you'll need one for the guest. If the motherboard has integrated graphics, you need to ensure those are enabled in the BIOS and set as the primary graphics there so that when Unraid boots, it utilizes that iGPU and then you can use your discrete GPU for the VM. If you don't have an iGPU on that system, you can try some more advanced guides to passing through the GPU:

Just want you guys to know that we're tracking all of these VM issues and I'm looking into them this week. Thank you for the reports!

I'm confused. The issue has resolved itself? The game is performing fine now? If so, there's no way that those clock speeds could be accurate while you're getting good in-game performance. Its likely a reporting error in the VM.

I completely agree with you on that sentiment.

Thanks for the feedback guys! I first noticed the anti-cheat problem when my favorite game, Escape from Tarkov, decided to prevent VM users from playing. Fortunately it wasn't a ban, but rather, just insta-kick from the game servers. Still very annoying but at least it wasn't a permaban. The hard truth is that eventually, game developers won't be able to ignore VM gaming users. This is a growing market segment that I only see continuing to grow over time. And with the ability to hide/mask things getting better and better, eventually it won't even be an option for them to ban based on VM detection.

Curious if you try a different game if you have the same or different results.

Please try to recreate the issue without the use of tdarr.

Unfortunately we do not have any 30-series GPUs for testing here, but we do see other users reporting success with this combination. I don't think your issue is the GPU. I think it is more likely tied to your Ryzen CPU. AMD CPUs have been notorious for causing weird performance oddities on random setups. Some users report everything working great, others have issues like you've described. The big things you need to try: 1) Disable all dockers, plugins, or any other custom 3rd party add-ons you have installed on your system and retest. 2) Did you properly isolate your CPUs for your VM? You can do this from Settings -> CPU Pinning page. If you've already done those exact things and are still having poor performance, I'm not sure what else to suggest other than changing the CPU/mobo.

I think you are legitimately running out of memory. I don't see this as a "runaway issue". When you use hugepages for VMs, that memory is reserved for the VM even when its shut down. That is the one major downside to using hugepages: you cannot dynamically utilize that memory. In addition, beyond the memory assigned to the VMs you have, memory is also utilized by QEMU/KVM for emulating components for those VMs. That utilizes additional memory. So between the 20GB being assigned to your Windows VM via Hugepages, another 2.5GB for your Linux VM, that leaves you with less than 10GB remaining for all of your applications and the emulation required for your VMs as well as any additional overhead for filesystem operations (which can vary). I think you're butting up against the upper limits of your memory usage and should consider reducing your Windows VM to 16GB (along with the hugepages reservation you created). All the best, Jon

You can create mount points under /mnt, but not /mnt/user.

Where are you installing Plex exactly? If its in a Docker container, do you have your Docker loopback file also located on the flash? You probably want to try moving all of that to one of your ZFS pools. Using a flash drive for loopback images or containers in general is probably unwise.

So on the Management Access settings page, you have Allow Remote Access set to Yes and the WAN port set to 14444. On that same page you have the SSL Port set to 443. You then logged into your Sky Router and configured a port forwarding setting to forward traffic from 14444 on the WAN to 14444 on your Asus Wifi device. Then you logged into your Asus and configured 14444 to forward to 443 on your Unraid server? That last part is really important. The last forwarding rule should forward from 14444 to 443, not 14444 to 14444. I think the issue is probably in your forwarding configuration.

Ok, so you're going to have to walk us through step-by-step what you did to get to where you're at and exactly where things fell apart. This isn't a standard configuration that we support just yet, but we can probably figure it out if you can catch us up as to what you're trying to do here.

Hi there, Boy that sounds like a complex environment! In short, yes, that is in essence how it should work so long as all the ports line up. Are you saying that's not working? If so, please attach your system diagnostics so I can review.

Hi there, Please reply to this thread and attach your system diagnostics. These can be obtained from the Tools > Diagnostics page. All the best, Jon

After adding the GPU, you may need to edit any VM that has a PCI device assigned to it. PCI device IDs can change when new devices are added, so you'll simply need to verify that before starting the VMs after adding the new device.

Yes, you can add a GPU and it will output graphics for the console.

Try this. Get a new flash drive. Use the USB creator tool on it. Try to boot Unraid and see if the webGui login works (http://tower or http://tower.local or by IP address). If that works, you know its something misconfigured on the flash. If it doesn't work, there is most likely something amiss with the hardware. If it works, then you can go through the steps you've outlined above.
