GPU passtrough error. tried google.. help please :)

[Andremelst]

I am trying to pass through an old Radeon HD5830 to a Ubuntu VM. I have checked that it is in its own IOMMU group, and that IOMMU is enabled in unRAID. but when i try to start my VM, i get this error.. any tip would be very much appreciated :)

Are you also passing through the card's audio?

I'm not sure this card will work using ovmf. You could try Seabios, but I don't think that is the problem here.

First try to add the below in between append and initrd=/bzroot in your syslinux.cfg.

Go to the Main page of unraid, click Flash and you can add it directly in the syslinux.cfg editor.

 

vfio_iommu_type1.allow_unsafe_interrupts=1
