Good Day, All

I do not know what is going on with PVE 8.0 and my 12th GEN, I have followed like 20 guides and form posts and still nothing wants to work.

Code:

Also look at the form posts so i am not sure what is going on. If anyone has an solution please let me know.

Thanks
 
Derek’s guide is pretty robust I followed it last week, I did find the sequencing was odd for me and I missed a couple of steps. Not sure if this will help, this is my resequenced version https://gist.github.com/scyto/e4e3de35ee23fdb4ae5d5a3b85c16ed3 (by they time I got to my 3rd node I was just copying my commands from this sequence and it worked first time). Good luck.

also delete and reclone the GitHub, maybe they introduced a bug….

Thanks for this but for some odd reason this is not working for me. Here is my iGPU

Your grub command line appears to be missing iommu=pt
( aka first two lines, maybe you made a typo on that one or missed it when you did the GRUB part of the process? )

I am not sure what is going on here. I did this all again as per your guide and i get this

Code:

Module verification error can be ignored. I have that too.

what else does that dmesg grep show you? Also try grepping drm to see what you see…
 
Oh one thought, don’t have anything plugged in the hdmi, don’t use usbc/tb didplay connected and update bios? (Yeah this is poke and hope troubleshooting, no more…)
 
For you reference, this is a working system.

Nothing is plugged in at all. Do you have the same igpu as me ?

root@pve01:~#

Have you also got your display to work on an windows VM at all ? If yes then i think i might have broken my Proxmox setup and might need to start all over again.

Code: 
root@pve01:~# dkms status
Error! Could not locate dkms.conf file.
File: /var/lib/dkms/i915-sriov-dkms/6.2/source/dkms.conf does not exist.
i915-sriov-dkms/6.1, 6.2.16-10-pve, x86_64: installed

Yes something is now broken :(

I only tested vgpu acceleration in win11
are you asking could win7 use the hdmi port? If so, my understanding is no vm can output to the hdmi. (Based on other forum threads)
also win7? You running MCE?

if you perform the steps from scratch you should be able to fix. also you can use dkms to uninstall the current module and restart, then redo all steps.
 
for reference.

Thanks again for your help and support here. Windows 11 is what i am going to be using. On my other post

https://forum.proxmox.com/threads/proxmox-remote-vm-access-locally.132935/

It seems you can do what i am looking to do. Not sure if an iGPU will work thou for this.

Let me see what i can get all done with this with an rebuild.

Do you have uninstall steps at all ?
 
revert the grub changes ?
try dkms uninstall and dkms remove as needed ?( i onky used these once I had rebuilt because I used new kernel and I wanted to remove old so my advice at this stage is no better than your own!)

Don’t confuse vGPU (sharing 1 gpu with many vms) with single device pass through (dedicating one whole gpu to one VM - this means host OS can’t use it too). They are different.

if you are expecting full gpu access then I think this is what you want https://forum.proxmox.com/threads/p...x-ve-8-installation-and-configuration.130218/ I am pretty sure vGPU can’t be used like you want, only dedicated pass through.

oh and https://forum.proxmox.com/threads/pci-gpu-passthrough-on-proxmox-ve-8-windows-10-11.131002/

complete newb to all this but would love to get SR-IOV working so I can setup 7 graphics cards to allocate to each VM (2 x Windows 11 and Linux Kali) like in the below guide.

I followed this guide but hoping someone could give me the hint I need to make this happen?
