[libvirt-users] snapshot anomaly

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 <domainsnapshot>   <name>snap</name>   <state>shutoff</state>   <creationTime>1485813671</creationTime>   <memory snapshot='no'/>   <disks>     <disk name='vda' snapshot='external' type='file'>       <driver type='qcow2'/>       <source file='/*var/lib/libvirt/images/serv1r2-savesnap.qcow2'/*>     </disk>     <disk name='fda' snapshot='no'/>     <disk name='hda' snapshot='no'/>   </disks> #  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? -- Doug Hughes Keystone NAP Fairless Hills, PA 1.844.KEYBLOCK (539.2562)
