I want to delete some old snapshots, but when I try to access the list of
snapshots in using the engine UI I get
"Uncaught exception occurred...Details: Exception Caught: html is null..."
The logs show the following
2018-09-29 18:42:50,953-04 ERROR

Any ideas? Can I delete the snapshots using virsh as a backup?
