I've just done that, and works as expected. Downtime: few minutes,
to move the XXX.conf file.

Plus, as a bonus:

a) volumes get created on NFS as QCOW file, so you need the thin space
  available on NFS server, not the thick one.

b) because volumes are files, if you also need to rename the VM, you
  can rename the volumes easily.
