I'm not sure how this snapshot got created, but, I cannot delete it, and
its presence prevents me from creating other snapshots. I don't know if
it was created by a command gone amok or something else.

# virsh snapshot-list serv1r2
 Name                 Creation Time             State
 snap                 2017-01-30 17:01:11 -0500 shutoff

# virsh snapshot-delete serv1r2 snap --disk-only
error: command 'snapshot-delete' doesn't support option --disk-only

# virsh snapshot-dumpxml serv1r2 snap
  <memory snapshot='no'/>
    <disk name='vda' snapshot='external' type='file'>
      <driver type='qcow2'/>
      <source file='/*var/lib/libvirt/images/serv1r2-savesnap.qcow2'/*>
    <disk name='fda' snapshot='no'/>
    <disk name='hda' snapshot='no'/>

#  ls -l /var/lib/libvirt/images/serv1r2-savesnap.qcow2
ls: cannot access /var/lib/libvirt/images/serv1r2-savesnap.qcow2: No
such file or directory

# virsh snapshot-create-as --domain serv1r2 snap --diskspec
vda,file=/var/lib/libvirt/flashimages/serv1r2-snap.qcow2  --disk-only
--atomic --no-metadata --quiesce
error: internal error: unexpected domain snapshot snap already exists

# virsh snapshot-revert serv1r2 snap
error: unsupported configuration: revert to external snapshot not
supported yet

Any idea for breaking out of this box?
