November 25, 20223 yr Hi, I hope i posted this is the right section. To keep this simple, I was previously on 6.11.1 and had a VM with my gpu passthrough working and decided to update after seeing Space invader's new video after the update it bonked my VM and it wouldn't run. I created a new VM with windows 10 install on it where it would run fine with the virtual display drivers but once I passthroug my GPU it doesn't want to start. here is the xml for the vm <?xml

to high jack this thread, but I'm encountering the same issue too.. i was from 6.9.2 then i upgraded to 6.11.5. .. then my Windows VM doesn't have a diplay anymore. and my CPU 4th core is always at 100%. I have attached above VM log. at first my migrated VM was not working so, I thought creating a new windows 10 VM from version 6.11.5, would make things work. but still I'm back to 0, my VM still has no display.
November 25, 20223 yr Author So the easiest solution i found was just to switch to Q35. I couldn't just change it and it would give me a error but I just made a new VM with q35 as the default and the gpu passthrough worked Thanks
January 17, 20233 yr @baby0nboardInSg I got my RX550 working after upgrade from 6.9.2 to 6.11.5 with these steps. Not ideal, but a good bandaid
