Which version of virt-df, from where?

What's the precise virt-df command that you're running?

libvirt doesn't have anything to do with virt-df, unless you're using
the -c or -d options of virt-df in which case virt-df will use libvirt
to look up the path to the guest disk image.  In any case, there's no
useful information in the libvirt log from running virt-df.

In addition to answering the important questions above, try enabling
debugging:
