I'm suprised  to see libvirt broken at all here.

AFAIR, the 'fd:' protocol inadvertantly gained support for targetting
plain files, which the deprecation aimed to then revert (remove). The
actual removal though seems to have targetted anything which is not a
socket, which includes pipes, which libvirt was using.
