Updated libvirt with:

Not its 2.module_el8.6.0+1087+b42c8331
Testing:
# virt-df -d kvm3551
But still, issue remains. Here how it looks like in /proc (all these socket/pipe symlinks
are broken):
# ls -lah /proc/$(pgrep -f libvirtd)/fd/*

It is generally more useful to use 'lsof -p $LIBVIRT_PID', so you
get readable names for sockets.
Also compare before & after so you can identify which is the new
"leaked" file.
Also is that a one time leak, or is a new FD leaked for every
virt-df command that is run ?

Daniel
