VM passthrough issue

[davemoreton]

Hi Guys,

 

Can anyone help me, i'm struggling a little with trying to setup a VM that will passthrough to my main monitor.

 

VM has been created, I have tried 2 video cards, one 6450 and a GTX 960.

 

So far i've had absolutely nothing out the display! I've used the techpowerup sight for a bios, binded the IOMMU's, am I missing something?

 

Thanks 

Dave

Have you tried all the different connections on the cards? Sometimes only one output will go live.

[davemoreton]

Really? crap no, it has a DVI port as well!

[davemoreton]

Naa, still get no output on all screens

[davemoreton]

Ok, small update on this, I’ve been going nuts with settings and created a windows 10 machine with the onboard intel UHD 630 in seabios and for a few times I managed to get the seabios screen come up!! It wouldn’t boot into windows but I did have a bios screen!

 

I then restarted the unraid server and will it do it again, nope! 🤨

 

has anyone got any ideas?

[Dmytro Piddubnyi]

Post your XML VM settings and Tools->System Devices(what iommu you use), also check that iommu enabled in the bios settings.
Check that you properly passthrough the GPU(bios/audio device with multifunction)

[davemoreton]

Managed to resolve this, for anyone else having this issue I had to add this to the sys config:

 

kernel /bzimage
append initrd=/bzroot earlymodules=vfio-pci video=efifb:off,vesafb:off gfxpayload=text
