Hello all. I just started tinkering with proxmox, and am trying to pass the integrated graphics to an Ubuntu VM.
I can't quite get it to work, so I'd like some help troubleshooting what's wrong.
This is running on a Minisforum TH50 (cpu: i5-11320h).
Essentially, I've tried every method I can for enabling the IOMMU, but adding a pci device to a VM through the management interface gives me the "No IOMMU detected, please activate it.See Documentation for further information" message.
I should note that my BIOS does not have a IOMMU or VT-d option, but Minisforum has said for other products that this feature is forced on and hidden in the BIOS. I've sent support an email asking if that is true for the TH50 as well, but I figured I'd still post this here in case I missed something else.
This is my kernel command line:
I haven't changed any other line in
I'm pretty sure I can get rid of the
The output of
and the output of
The "Skip IOMMU disabling for graphics" seems important, but I don't know what it means.
I also installed
Have I made any glaring mistakes? If not, what should my next steps be?
Thanks
