Description Mr. Beedell, Roke Julian Lockhart (RJLB) 2025-05-14 17:15:36 UTC 
Description of problem:
Per [`wiki.gentoo.org/wiki/GPU_passthrough_with_virt-manager,_QEMU,_and_KVM#Windows`][1], I added the undermentioned to my `PRETTY_NAME="Fedora Linux 42 (KDE Plasma Desktop Edition)"` VM in `virt-manager-5.0.0-2.fc42.noarch` in order to gain GPU passthrough. Instead, I lost my display output:

> ~~~XML
> <hostdev mode="subsystem" type="pci" managed="yes">
>   <source>
>     <address domain="0x0000" bus="0x03" slot="0x00" function="0x0"/>
>   </source>
>   <address type="pci" domain="0x0000" bus="0x07" slot="0x00" function="0x0"/>
> </hostdev>
> ~~~

Consequently, I SSH'd via my smartphone into the superuser account, and initiated a `shutdown`. This appeared to hang, for after a few minutes, it hadn't completed, but I couldn't SSH anymore (because it was, presumably, in the shutdown log). Consequently, I hit the MB's RESET_SW. After an update that was scheduled for that reboot, GNOME Abrt appeared at login with this report.
