Remote Gaming! (and Video Encoding using Proxmox and GPU Passthrough)

Are you looking to build a remote gaming machine and passthrough your GPU to a virtual machine? Do you want to use GPU acceleration for transcoding Plex or Adobe Media Encoder? Do you dream of setting up Steam Link or Remote Play In Home Streaming and streaming games to any screen in your house? If so, this complete step-by-step guide of how to passthrough your Nvidia or AMD video card through to a guest VM using Proxmox VE! If not, well, please watch this anyway.

"go out and buy 2 video cards" hahahaha good one

[MagecraftLP]

Good video. But I recommend to do some things differently after I experimented around a bit:
1. BIOS Settings: SVM/VT-d and IOMMU/VT-x have to be enabled. Enable SR-IOV and ACS if you have those options.
IMPORTANT: Before you install Proxmox at all "CSM" has to be disabled in the BIOS and "Above 4G Encoding" has to be enabled. If your VMs dont work with these setting reinstall proxmox completely! This fixed the stupid Code 43 for me!
2. 3:11 If you have an AMD CPU use amd_iommu=on instead of intel_iommu=on. This is neither pointed out in the video nor the documentation. Please fix that!
3. DONT CHANGE AN EXISTING VM! Install the VM as OVMF + q35 from the beginning. Don't change an existing VM into that. It causes the VM to not start.
4. If your VM refuses to start delete ALL IDE devices and replace them with SATA ones if neccesary.
5. You might need to add the GPU to the VFIO. To do this run 'lspci -v' and get the ID of the GPU and the HDMI audio device. Then run 'lspci -n -s <ID>' for both the vga and audio device. This will give you the vendor IDs of the devices. These should look like that: '10de:10f0'. Then run 'echo "options vfio-pci ids=<vendorID1>, <vendorID2> disable_vga=1"> /etc/modprobe.d/vfio.conf'. After that run 'update-initramfs -u'
 6. Don't use windows RDP for remote gaming. Use something hardware accelerated like Parsec. Steam and NVIDIA also have options for gamestreaming.
Hope this helps.

absolutely PERFECT choice of background music, and volume level. I can hear the music, its nice on my ears, But you are still **very** audible. 10/10 Please teach others this sort of audio balancing.

This may be an older video, but just wanted to say thanks for the guides!! I've now got a Proxmox 7 setup, 4 WD 4tb red plus drives, too many SSD's, a Windows VM, an ubuntu VM, and about to add a FreeNas server all onto one machine. This is just awesome stuff! Thank you so much!

[Midway]

Thank you for you video's, they are so helpful. I'm a software engineer and have seen so many tech tutorials. I have to say yours are among the best and clearest I've ever seen. Keep up the awesome work Tim!

[Marfprojects]

WARNING. 3:04
This is something to keep in mind. Enabling ACS override can cause a VM Escape because the IOMMU groups are NOT separated properly ACS can fix this by forcing them to be separate groups, but it can cause that a vm can access other memory addresses even though they are not supposed to. If you don't do anything stupid its fine, but be aware if a malware infects the vm, its possible to do a vm escape.

any other then that, great video!

Thanks for including the CLI commands, I feel like a lot of people leave those out. I really appreciate the effort and attention to detail.

[Diastolicflame]

actually really informative. I've always thought about virtualization because I run like multiboot setups for different things and this seals the deal if I can pass through my gpus.

[johngrabner]

Wow, this would be so cool for deep learning. Deep learning has different environments that Gpu passthrough would be perfect for. Also instability causing crashes would be isolated to a vm

[akkshep]

Thank you SO much for this video! I spent the last few days in forum hell trying to get this working properly. Subbed.

[emiellr]

Hey Tim, small yet important remark: you mentioned you need vt-x for intel, but to use pci-e passthrough you also need vt-d. Without that you can still make a vm and it will work just fine, but you can't pass a gpu.

[TheRealHiddenNinja]

Regarding Remote desktop, try looking at the following:
Parsec (which is good, but the game must be running first)
moonlight-stream (depends on the GPU, as it uses NVIDIA Shield)

Other than that, loving the video! :)

[murtza.rehman]

You have so beautifully given away such a wonderful setup and it all felt as easy as casually playing a Video Game. Amazed !

[alexzendermarunsai]

Thanks man. Just what I need to start my promox vm gaming journey. Subbed.

[kylecurry]

Tim, you're the man! Nice tutorial, I haven't been a gamer since I was in my teens, but much has changed in the world of gaming, and my son's are now into the latest games, some of which I'm aspiring to run from PC exclusively and so given I'm big on backups, running the game from my PVE home server will be the premise here, this helps alot!

BTW, I've rarely had to use the "q35" CPU option, but I have done this in PVE before with an OSX system :-)

[goteamgorilla]

Looks like I have another Proxmox "project" this weekend. Thanks Techno Tim!

[vincenthu-byoh]

I found i can't start my vm after i changed the vm 's BIOS to OVMF(UEFI) and Machine to q35, and i tryed to remove the CD/DVD drive that contains virtio image iso, it could be started, but it didn't configure its network automatically

[smealson]

Yesterday i used your tutorial successfully, thanks a lot for this. i tried a few tutorials on this case before but the only one that runs on my machine is yours.
i wish you all the best and a great year !

[lmaoroflcopter]

I think if you use a low latency "meant for game streaming" method of connectivity like parsec the latency you're seeing will be dramatically reduced. A lot of that is probably the overheads in RDP.

This is a sweet guide though. Looking to use this for some spare hardware I've got here.
