Description Mr. Beedell, Roke Julian Lockhart (RJLB) 2025-05-14 17:22:17 UTC
Description of problem:
Like [`id=2366277`][2]:

:	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.

Comment 15 Fedora Release Engineering 2026-05-06 12:56:01 UTC
This message is a reminder that Fedora Linux 42 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 42 on 2026-05-13.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '42'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version. Note that the version field may be hidden.
Click the "Show advanced fields" button if you do not see it.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 42 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

This is, likely, an example of what https://github.com/ValveSoftware/steam-for-linux/issues/13165#issuecomment-4392845808 describes, probably caused by my own misconfiguration.
