AMD ryzen 7900 onboard GPU passthough possible?

[letalis]

All,

been digging on these forums for a few day's now, but so far I did not end up with a positive result.

What I would like to accomplish is to attach a monitor to my Proxmox VE server that shows the output of a windows VM. I don't want to install an extra VGA card, only want to use the onboard.

Is this possible? Any tips will be appreciated!

The error message in de VM:

 

[JohnR82]

So Proxmox 8 will not install through ASRock IPMI and I'm pretty surry it is in fact the unstable IPMI but the host is trying to blame Proxmox for being to legacy to be installed With Ryzen 7900

 

[JohnR82]

Can someone advise on how else to get Proxmox 8 installed without remote KVM?

 

[x130844]

It is impossible. I have tried for weeks now.
and I have been successful with other configs. just not AMD iGPU Ryzen Raphael.

 

[JohnR82]

As suspected, host was wrong. Installed and created a custom cpu. So far, so good

Ryzen 9 7900 12 Core 24 Threads 128GB DDR5

I had to install in debug mode and every thing went fine. Not Seeing the Ryzen in the CPU list when creating VM I added the custom file and set up a Custom Ryzen 7900. So far everything is fine and it's really fast but I haven't had much time after creatng a VM to play with it much.

Hopefully there won't be too many issues as I get to test more!

I think I seen some instructions for the GPU pass through with the Custom CPU build but I don't remember if it was the actual Proxmox docs that had it.
