libvirt.libvirtError: internal error: libxenlight failed to attach pci device 0000:04:00.0

Having the ram on either 1848MB or 2048MB didn’t change anything, unfortunately.

Sorry to hear. What I do in these situations is to run in dom0 terminal sudo journalctl -f, then trying to start qube, following dom0 terminal. When it finishes, ctrl+c in terminal, and copy paste the part of the journal here in order to be helped. It is very rare not to be able to start win qube under neither circumstances.

It’s np. I kind of break every bit of technology around me by nature, so… lol. But anyways, I ran the command, booted up the vm, the issue happened, then it closed – but the output was… a bit long. so I threw it in an unlisted Pastebin just bc I didn’t want to spam this thread – anyways, here you go: [novum@dom0 Desktop]$ journalctl -fJan 01 19:01:01 dom0 run-parts[135901]: (/e - Pastebin.com

I am seriously hoping this works, because I’m contemplating dual-booting with windows if this fails… but I know that compromises my security 10 fold, so I’m hoping we can figure this out. Which I just wanted to shout out a thank you for everybody that’s tried to help so far, as well as anyone who may. Thank you guys.

Also, instinct tells me somebody may ask if I tried to custom install – I did not. I used the average 4.2.0 iso, flashed it to a thumbdrive, then installed it. Nothing custom about it – even though the whole “hostname=?” is the way it is and all those.

My bad everyone – I was a complete idiot and swapped the two gpus in my mind… so I was trying to hide, passthrough the active gpu. My sincere apologies. That said, there still is an issue that I’m in need of help for – I’m making a new thread now, since it’s not related to this fully anymore.
