Nice. Proxmox rocks. I’m really interested to see if you can say there is any noticeable performance drop in the graphics. I think there should not be but I don’t know enough. Thanks again.
GREAT intro for a beginner proxmox user!! However, incase this helps anyone, here are some issues i ran into: 1. had to use exact virtio drivers iso as linked in this video (other releases from fedora were missing scsi for me) 2. had to check "QEMU agent " under system, during initial VM configuration 3. when installing win11, i had to shift + f10 to open CMD in win installer and then force network bypass using oobe\bypassnro 4. when changing display under hardware in proxmox web GUI, i had to also reboot node to avoid QEMU failures 5. as a noob, forgot to readjust boot order many times lol. Hope this helps any other noobies, and if you have suggestions please let me know :)
After watching dozens of videos about PROXMOX GPU Passthrough, I came to the conclusion that this video is the most detailed and faithful to the process.
This tutorial works great. I've actually installed win 11 on the desktop as a vm with direct passthrough of the displays attached to the gpu, so on the surface the pc looks like a normal windows machine, but underneath it's running proxmox with a few more linux vms. (don't forget to start the vm at proxmox boot (VM->Options->Start at boot = Yes) I've also tried to do this for linux vms with ubuntu and pop os, but with no success. I've followed a few guides, but nothing really works for me and each guide is different in the changes they make. If you happen to know how to do this tutorial to linux that can pass through all the way to the display that would be awesome. I prefer running linux for development and I don't really want to have a dedicated machine for it, so a linux vm like this windows vm would be great. Thanks for sharing. I learned a lot from you
virtio block has better performance in windows and can be installed with virtio iso driver as well, you should put writeback with discard, ssd emulation and iothread
If you have NVIDIA graphics card error 43 on AMD platform, change the GRUB line to such GRUB_CMDLINE_LINUX_DEFAULT="quiet amd_iommu=on iommu=pt pcie_acs_override=downstream,multifunction nofb nomodeset video=vesafb: off initcall_blacklist=sysfb_init" and update-grub, restart proxmox, I don't know if it's the most optimal but it works, you don't have to reinstall the Windows virtual machine, just reinstall the NVIDIA drivers.
I've done exactly everything in the video, with no errors, and get back into windows but when i go to task manager I don't see a GPU, any reasons why? Help plz specs: 2* E5-2670V3 cpu jinsah dual x99 f2 mobo gtx 1080 gpu
Legend, thanks mate. This worked a treat. One issue I was having in case anyone else comes across this, make sure you unplug any displays connected to the graphics card being passed through before booting the machine into Proxmox. My VM wouldn't boot with a display plugged into the GPU. Adding the GPU in the hardware settings of the VM tipped me off as "PCI-Express" ticket on vs off would be the different between a successful VM boot, and not. I hope that helps someone.
Excellent!! Please answer this question: where did you find the string to insert in the "args: ... hv_vendor_id=NV43FIX..." directive inside the 100.conf file? Thank you so much for your kind support!
I noticed you have FQDN ending with .local. Something I learned a couple years back is that having a zone ending with .local, android devices will not be able to resolve due to how it is used with mDNS.
Appreciate your video and detailed guide. I don't like the word idiot in there, because someone who don't know how to do it is not automatically an idiot.
@@michaelamos75 no. Ignorant is someone who knows that something does exists (like the Earth is a globe not flat) and then ignores all the evidences. Instead of idiot I would say noob. Totally inoffensive.
Hi, First thing I want to say is sorry for my English, it’s not my native language. Thanks for understanding 😊 I really like this video. Guide is very clear and easy to follow. I’m trying convert my PC to proxmox servers with multiple VM’s. Some of them will run in a same time (nas, plex, home assistant), some of them will run VMs with different OS (primarily MacOS and Windows). And I won’t use Windows and MacOs in a same time, that’s why I want to passthough as much things as possible to each of them to use them as a normal daily computer. To switch between VMs I plan to write some script in python that shuts down one VM before starting second. If you like an idea and want to cover it in a future videos it would be awesome 😊
While I am grateful for the video, I do have one thing to nitpick. I hate it when people make a tutorial and then just say "just copy paste this into the console. Now copy this" without explaining what exactly you're accomplishing with those lines. That builds a false sense of blind trust and basically shuts the viewers brain off "I don't need to think or understand, I just need to follow step by step."
editing, great! I find it hilarious that Brandon is the only one I see using Nano. If it wasn't for him, I wouldn't know about it. Settling on Helix right now for me.
the general rule of thumb is one gpu per vm, if you have an nvidia enterprise/server card, it should have vGPU capabilities, which would allow for splitting the gpu amongst multiple vms, this is an entirely separate technology though, you'd need to look into it. AMD has MxGPU but that works a bit differently and might not apply the same way. there is a patch on linux machines that allows for consumer geforce cards (up to the 20 series) to have vGPU enabled on them, so you could also look into that, but idk much about it.

14:53 - why don't you just mount 2 CD/DVO instead of jumping?
Thanks for the idiot proof guide. If i have 2 pci-e graphics card, no integrated graphics. Am i only able to pass 1 gpu only to a VM? Does proxmox have to have its own dedicated GPU? Thanks
Sadly, yes proxmox needs to use the boot video card for itself. That's why I tossed a cheap video card in a unused slot so I could use my Nvidia card and AMD card for different VMs.
IT WORKED! 1st time through :) I did lose console view at the end but RDPed into it and loaded the drivers from Nvidia and all is well. Perfect Guide :)
I don't know what is wrong with my setup. I am trying to make it work on Gigabyte X570 ITX mobo, R7 3700X and RTX 2060/GTX 970. Every try I ended up with no display output/blackscreen on both GPUs. Luckly no code 43. Did you manage to have a physical display output?
@@GOPACKERSJT Yes, I had to add this script to cron to execute at startup: echo 1 > /sys/bus/pci/devices/0000\:0a\:00.0/remove echo 1 > /sys/bus/pci/rescan Good luck :)
excellent guide but I dont know why all of this has to be so yanky and manual, I mean its such a basic thing to do so why is there not just a gui with a view boxes to check....
If i have a gpu connected and a fresh install and i type lspci in shell will i see the GPU or do i have to do all the grub and iommu setup first. Im trying to determine if i have a hardware issue.
Cool guide. Thanks for the content and hard work. Be well.

I gotta problem. I've installed windows 11 In Proxmox with GPU Passthrough successfully. But only I can use in remotely. I saw another videos from another TH-camrs that get video in the same GPU Card. But I only get black screen. Might be i missing something? Thanks
What's gaming like with this, with the mouse and keyboard inputs, any lag? I tried to Looking Glass working to have Linux has my Main OS and Windows in a VM With GPU Passthrough for gaming, but couldn't get it to work.
craft computing, LTT and other youtubers made video on VM gaming. for lowest latency use Parsec as a remote desktop and connect host and client over cable. The only issue with gaming on a vm is AntiCheat. Valorant doesnt work in a vm and Rainbow Six has been banning VM gamers.
@@AIC_onyt actually sunshine moonlight is way better than parsec, supports almost every gpu,and has almost zero lag, depends on your Ethernet cable speed,i use an cat 8 and i I haven't seen any lag,plus it doesn't consumes your internet,so you can play offline
I "accidentally" got the same mobo as yours. I'm gonna get a Gigabyte RX580 8GB. Some said the GPU does have the reset bug, some doesn't. I need a suggestion please!
hi can you please answer my question, I would like to have windows 11 and mac OS in one computer, I have a 1TB SSD right now I have windows 11, so can I create a partition for proxmox and install it on it, will the data on my windows 11 get lost?
It's not working man, I completely destroyed my proxmox, when i hit start vm it's restarting proxmox, and is starting in a weird way, with errors and grub, no longer system boot, how can i undone what i did?
I want to use my old GTX 960 as the host GPU and a XFX RX 6800XT as the VM GPU. This is with a Ryzen 9 5900XT on a Aorus B450 board. The bottom PCIE slot is only x4, so I'll put the 960 there since it'll never need to do a whole lot. The top x16 slot seems to be in an isolated IOMMU group, so 6800XT there. I'm going to try that this weekend, has anyone done something similar? Any issues with Radeon passthrough?

So, doesn't look like I can use this to create a Ubuntu 22.04.2 VM running on windows 11 Host right? All i see is win virtual drivers, no linux virtual driver? please help clarify.
Thank you TechHut for that Video, and also to everyone else that is contributing to solving problems for GPU passthrough error codes! It can be such a struggle. I tried so many things to resolve Error 43 inside the Windows Device-Manager. The solution simply was disabling Resizeable Bar in my BIOS/UEFI ! I'm so glad it is working now! My Setup: Im am using Proxmox on a local machine with GUI - a possible but unsupported thing. Ryzen 3900X 1st GPU Radeon 6900XT (for passthrough) 2nd GPU Nvidia GTX 1650 passive card with 75Watt (used for host and enabled for X11 Display) Asus X570 TUF Mobo
@@AiresMPunfortunately I reverted the setup some time ago, because the performance wasn't what I expected, some applications and games were fine, but some had a big performance loss via passthrough - it's still considered experimental I guess Did the VM boot when you had resize BAR on? I would try configuring the GPU as a new one inside Proxmox after disabling resizeBAR and check/follow each steps from a guide. Maybe you missed something like blacklistung the driver for the host? Could be a lot of things honestly! Also check the logs from Proxmox after the startup fails (/var/log/syslog)
Very, very good video! Thnak you! Atm I have the problem, that I dont see the gpu in my win 10 vm under task manager. I followed every step and have read the entire reddit post. Maybe you have an idea
it worked! huzzah! no idea why but when i followed Craft's two guides, one for linux and one for windows (in which he couldnt get it working, lol), windows could detect my 1630 in task manager but after installing the drivers things got CRAZY SLOW. like, booting took 3 minutes to open my 5 apps and i still couldnt hw transcode and even direct play was slow. dozens of threads over the internet about this but no real solutions. so i just nuked my VM, started from scratch with your guide and it worked. i won't question why, you did all the same steps as the other guides, but in a different order and in the end i don't care why it worked. you're the man, thanks a lot. pulling my hair out over this one for a while now.
Thanks for the nice clear explanation without skipping steps! I guess later on you can connect a monitor to the AMD gpu and use that? I mean, instead of connecting to the virtual machine via the remote-desktop? If using an external monitor, would it be necessary to also pass through the HDMI or is that using the same PCI address?
I have that exact setup! Same gpu and bios. I am working on getting my gpu passed into an lxc ubuntu install running docker so I can pass my gpu through to containers.
I already have a win11 installed and running before adding a quadro p4000 gpu and I've done all the steps in this video up to starting the VM. When I add the gpu in the hardware it does not let the VM start
nvm, found it. just tick the primary GPU. for keyboard and mouse, just add usb devices. also for sound, add another pcie device, but this time for the audio.
Would this process be different for an LXC container and an Nvidia GPU? If so, could you point me in the right direction to a guide? I believe I am so close. Instead of updating ../qemu-server/100.conf I am editing ../lxc/100.conf, but I assume the lines I add in this file are different than what you added and there might be some steps that need to be done prior to this. Or would all of this be easier if I installed a VM as you did (i.e. ubuntu server) and setup GPU passthrough (the same as this) to that VM? If so, in order to setup plex and start apps in the VM, should I use docker? Will the GPU passthrough work on everything in the VM (i.e. docker, docker containers)?
I don't think I heard but do I need a 2nd GPU for this? It's probably a better idea to have a 2nd one but since my proxmox sits headless anyway would this work for a single GPU setup??
@@TechHut Awesome, very good to know, every time I looked into this in the past "everyone" claimed a 2nd GPU was a requirement :) it would be so cool to be able to have a VM just for OBS recording (I like to use NDI a lot!)
My Dear TechHut, I have a question for you. Have you try to do the same in a linux machine ? Because usually passthrough to windows work quite well. With Nvidia and AMD. But passtrought to Linux is another story. With Nvidia and the official driver is ok. The performance loss compare to windows is quite significant. And with AMD I cannot say I have not been able to make it work yet ! :D
I use HP Z420 with Intel Xeon E5-2680v2, and 2 GPUs including RX 570 (4Gb) and Nvidia GT730 (2Gb), I tried to follow your guide but I can't passthrough GPU when I set the display to "None", the VM can't be started and it shows that "VM 1001 qmp command 'set_password' failed - Could not set password TASK ERROR: Failed to run vncproxy." Do you have any suggestions for me, please? Thank you!
I can passthrough now, but the last step when you set display to none, if I do that, the VM will not be started, I have to set it as "default". I can see in Task manager the GPU is RX 570 but in "dxdiag" it doesn't show RX570 there. How about you please!
Hi, I'm trying to get my gpu passthrough to work and followed the guide/video, but when i boot into windows and look in task manager the gpu is not there.
If your one those lucky people interested in starting your own home lab techhut is giving good tutorial, you might want to conduct some additional research depending on your specific hardware because some additional steps maybe necessary to ensure proper pci-pass through. If you have one those with higher end gpu please remember you might run into reset bug which won't allow you restart vm without resetting the entire server.
could this work with a local monitor connected, and with 2 USB ports passed through as well? So that I could run a 'local' machine from my proxmox server whilst it also runs several other VMs?
Hi, I did everything as in the video, but when I start the VM I get an error: TASK ERROR: cannot prepare PCI pass-through, IOMMU not present. Can anyone come across and help me with the solution?
Excellent video on how to use one GPU with Proxmox and using Davinci Resolve to test the GPU pass-through performance. It would have been nice to see how Resolve performs with playback or another typical editing graphics-intensive function with GPU passthrough.
Test it and it work on my Radeon 6600XT however if I do intense graphics usage like game.. RDP will get cut off multiple times with error. Any solutions?
good guide, i had followed it frist time it work on my rtx 2080ti with cpu host 3700x it work fine but after i accidentally remove the ip address on the host had to re install proxmox and the win 11 vm , then follow again your guide the nvidia driver was giving error code 43, oddly after i disable the blacklist.conf and the vio...something where you put the gpu pci address, them i boot into the gpu with direct output on the gpu hdmi

@@AiresMPunfortunately I reverted the setup some time ago, because the performance wasn't what I expected, some applications and games were fine, but some had a big performance loss via passthrough - it's still considered experimental I guess
Did the VM boot when you had resize BAR on?
I would try configuring the GPU as a new one inside Proxmox after disabling resizeBAR and check/follow each steps from a guide.
Maybe you missed something like blacklistung the driver for the host?
Could be a lot of things honestly!
Also check the logs from Proxmox after the startup fails (/var/log/syslog)
how to forward a video card on several virtual machines?I have device '0000:05:00.0' is already in use by VMID '1110'
Does proxmox allow stable emulation of a virtual machine with more RAM for use then the host has physical RAM? If not , does anything?
uefi bios is not needed, only machine type
Very, very good video! Thnak you!
Atm I have the problem, that I dont see the gpu in my win 10 vm under task manager. I followed every step and have read the entire reddit post. Maybe you have an idea
it worked! huzzah!
no idea why but when i followed Craft's two guides, one for linux and one for windows (in which he couldnt get it working, lol), windows could detect my 1630 in task manager but after installing the drivers things got CRAZY SLOW. like, booting took 3 minutes to open my 5 apps and i still couldnt hw transcode and even direct play was slow. dozens of threads over the internet about this but no real solutions. so i just nuked my VM, started from scratch with your guide and it worked. i won't question why, you did all the same steps as the other guides, but in a different order and in the end i don't care why it worked. you're the man, thanks a lot. pulling my hair out over this one for a while now.
when boot my VM display black screen notification: "guest has not initialized the display (yet)"
Thanks for the nice clear explanation without skipping steps!
I guess later on you can connect a monitor to the AMD gpu and use that?
I mean, instead of connecting to the virtual machine via the remote-desktop?
If using an external monitor, would it be necessary to also pass through the HDMI or is that using the same PCI address?
I have that exact setup! Same gpu and bios. I am working on getting my gpu passed into an lxc ubuntu install running docker so I can pass my gpu through to containers.
How to do this for the integrated gpu?
I already have a win11 installed and running before adding a quadro p4000 gpu and I've done all the steps in this video up to starting the VM. When I add the gpu in the hardware it does not let the VM start
Good vid!
It's just too much of a hassle to make it work. Just installing it normal makes life easier :D
can we use HDMI as the video output of this guest? also keyboard and mouse.
nvm, found it. just tick the primary GPU. for keyboard and mouse, just add usb devices. also for sound, add another pcie device, but this time for the audio.
How can I integrate the GPU to my Linux in VirtualBox?
Would this process be different for an LXC container and an Nvidia GPU? If so, could you point me in the right direction to a guide? I believe I am so close. Instead of updating ../qemu-server/100.conf I am editing ../lxc/100.conf, but I assume the lines I add in this file are different than what you added and there might be some steps that need to be done prior to this.
Or would all of this be easier if I installed a VM as you did (i.e. ubuntu server) and setup GPU passthrough (the same as this) to that VM? If so, in order to setup plex and start apps in the VM, should I use docker? Will the GPU passthrough work on everything in the VM (i.e. docker, docker containers)?
Quit tip for those proxmox has single GPU, need to add "initcall_blacklist=sysfb_init" to kernel parameter
I don't think I heard but do I need a 2nd GPU for this? It's probably a better idea to have a 2nd one but since my proxmox sits headless anyway would this work for a single GPU setup??
This setup is a single GPU :)
That's very cool
@@TechHut Awesome, very good to know, every time I looked into this in the past "everyone" claimed a 2nd GPU was a requirement :) it would be so cool to be able to have a VM just for OBS recording (I like to use NDI a lot!)
@@TechHut Awesome, I'll give it a try :)
So if i wanted to setup linux with windows VM and im planning on upgrading my GPU should i go nvidia or amd do you think?
any chance of a prox mox virtual machine with GPU and USB pass through for a Virtual Mac?
My Dear TechHut,
I have a question for you. Have you try to do the same in a linux machine ?
Because usually passthrough to windows work quite well. With Nvidia and AMD. But passtrought to Linux is another story.
With Nvidia and the official driver is ok. The performance loss compare to windows is quite significant.
And with AMD I cannot say I have not been able to make it work yet !
:D
Ventoy is an open source tool to create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files.
Great work and accessible guide, I appreciate your hard work.
Can i get output directly from the GPU?
The video goes too fast to follow and the Guide is set to Private. Overall kind of useless.
Reddit pages are on strike.
Any reason why this won't work on EndeavorOS?
I presume you can plug a monitor in and it will output display??
Can I use the same GPU for multiple VMs?
thank you for posting this i love you baby you are my favorite
I use HP Z420 with Intel Xeon E5-2680v2, and 2 GPUs including RX 570 (4Gb) and Nvidia GT730 (2Gb), I tried to follow your guide but I can't passthrough GPU when I set the display to "None", the VM can't be started and it shows that "VM 1001 qmp command 'set_password' failed - Could not set password
TASK ERROR: Failed to run vncproxy." Do you have any suggestions for me, please? Thank you!
I can passthrough now, but the last step when you set display to none, if I do that, the VM will not be started, I have to set it as "default". I can see in Task manager the GPU is RX 570 but in "dxdiag" it doesn't show RX570 there. How about you please!
I dont have the iommu option in my bios at all, i have an A320M -A pro
I must have 2 PCIE video cards so I can pass through 1 in case I do not have a onboard one?
IZLEDIM
Hi, I'm trying to get my gpu passthrough to work and followed the guide/video, but when i boot into windows and look in task manager the gpu is not there.
If your one those lucky people interested in starting your own home lab techhut is giving good tutorial, you might want to conduct some additional research depending on your specific hardware because some additional steps maybe necessary to ensure proper pci-pass through. If you have one those with higher end gpu please remember you might run into reset bug which won't allow you restart vm without resetting the entire server.
could this work with a local monitor connected, and with 2 USB ports passed through as well? So that I could run a 'local' machine from my proxmox server whilst it also runs several other VMs?
Its windows 11 or Server 2022, not windows 11 of 2022 :D
Hi, I did everything as in the video, but when I start the VM I get an error:
TASK ERROR: cannot prepare PCI pass-through, IOMMU not present.
Can anyone come across and help me with the solution?
4 months late here, sounds like u need to enable iommu in your bios
Will this work if i only have 1 gpu no internal vidro card.
??
@@kcoppa if my server motherboard has no insternal video card. Only have gpu in the pci slot.
@@WRod1464 Sorry. I just put the question marks so I would also get the answer. I search the comments and this does work with only 1 GPU.
@@kcoppa thanks
Hello, could you make a tutorial on how to spin-down hdd in Proxmox? thanks in advance!
you need to have an updated written tutorial-- the reddit guide is outdated.
How we change hwid everytime?
Excellent video on how to use one GPU with Proxmox and using Davinci Resolve to test the GPU pass-through performance. It would have been nice to see how Resolve performs with playback or another typical editing graphics-intensive function with GPU passthrough.
Can you plug a monitor in the hdmi port will it output
Can you do this to a existing Windows 10 installation?
Test it and it work on my Radeon 6600XT however if I do intense graphics usage like game.. RDP will get cut off multiple times with error. Any solutions?
sunshine moonlight it's your solution
good guide, i had followed it frist time it work on my rtx 2080ti with cpu host 3700x it work fine but after i accidentally remove the ip address on the host had to re install proxmox and the win 11 vm , then follow again your guide the nvidia driver was giving error code 43, oddly after i disable the blacklist.conf and the vio...something where you put the gpu pci address, them i boot into the gpu with direct output on the gpu hdmi
what's your performance on gaming?in a normal Windows machine I get 500-700fps,but in proxmox im getting only 40-50fps with same settings,you too?
Really awesome sharing
