Jonathan, thanks for this disturbing report. For some reason, Vdsm fails
to parse libvirt's output.
Could you share your libvirt version as well the output of
for d in `virsh -r nodedev-list`; do echo ====$d====; virsh -r nodedev-dumpxml $d;
done
if all seems like valid xml, can you add the following print() and run
`restore-net` again?
diff --git a/lib/vdsm/hostdev.py b/lib/vdsm/hostdev.py
