Anything apparent via journalctl?
Discussion
nothing i could see, it looked like all the virtio binaries and other required binaries were installed and systemd services were running.. ..i even tried using the Arch LTS kernel
i don't use GPU passthrough, i've always used the virtio GPU within virt-manager.. ..thanks for the Claude feedback though, i will try this experiment on a different machine at some point, for now i just reinstalled Debian so i can use my main workstation in a stable state
