Hi Level1
Having some issues here, Been trying to setup a Windows VM with QEMU/OVMF/GPU Passthrough
Some system info
AMD Ryzen 7 2700x
32GB Hyper Predator RGB @3000mhz
Zotac RTX2080(Host)
GigaByte Arous RX580 8GB(Guest)
Manjaro 4.19.49-1-MANJARO
So far i have got all the packages installed for QEMU and Have configured OVMF UEFI
I can boot a VM and install windows to a virtual disk but i can not passthrough the GPU and boot of a disk that already has windows installed. Tried multiple ways of doing this and i get the same error on windows
INACCESSIBLE BOOT DEVICE
Any help appreciated
Thanks

When you installed Windows, did you only have the disk that would become the C drive plugged in?
Can you paste your XML?
Also, do you have both the GPU and virtual display connected to the VM? if so, watch the virtual display when you start it.

And Yes the Virtual display is still connected and it shows nothing on boot, switched to hdmi and its blank as well, the UEFI boots when the card is removed from qemu
Your XML looks good at first glance.
I’m about to leave my office. Just wanna give you a heads up. I’ll be incommunicado for a bit.
Is there a DVI port on the GPU? Can you check that one?
Does this drive boot fine with no GPU attached, just spice? I don’t think it’s the GPU, just wanna check. I’m not super good with windows issues. (not much of a windows user)
The drive will boot, but windows doesn’t like it, gives me the error of inaccessable boot device. The current xml is something im testing, installing windows to a spare HDD in my system.
Before for drives it was
<disk type='block' device='disk'>
<driver name='qemu' type='raw' cache='none' io='native'/>
<source dev='/dev/sdc'/>
<target dev='vda' bus='virtio'/>
<boot order='2'/>
<address type='pci' domain='0x0000' bus='0x06' slot='0x00' function='0x0'/>
</disk>
Okay, so then this is 100% a windows issue. I’m not a pro with this one. I’d troubleshoot this as if it’s a normal Windows issue.
Got windows to boot now, now GPU isnt working on the VM and i am unsure on whats causing it
Any idea to what might be causing the black screen?
Are the drivers working? What’s it showing in Device Manager?
Heres the thing, it will boot without gpu passthrough, but with passthrough. complete blackscreen
Hi were you able to fix this?? Try adding “” under features. I had the same black screen problem. But my card was a Nvidia card for quest not amd like you mentioned.
