How to delete a VM with snapshots

cy_88

A note about error: “cannot delete inactive domain with snapshots”
　　You cannot delete a VM with snapshots. For example:
# virsh undefine --domain openbsd
Sample outputs:

error: Failed to undefine domain openbsd
error: Requested operation is not valid: cannot delete inactive domain with 2 snapshots

　　To list snapshots, enter:
# virsh snapshot-list --domain VM_NAME
# virsh snapshot-list --domain openbsd
Sample outputs:

Name                 Creation Time             State
------------------------------------------------------------
3sep2016             2016-09-02 13:38:18 -0500 shutoff
3sep2016u1           2016-09-02 15:04:50 -0500 shutoff

　　The syntax is as follows to delete snapshot:
# virsh snapshot-delete --domain VM_NAME --snapshotname SNAPSHOT_NAME
To delete both snapshots, enter:
# virsh snapshot-delete --domain openbsd --snapshotname 3sep2016
Domain snapshot 3sep2016 deleted

# virsh snapshot-delete --domain openbsd --snapshotname 3sep2016u1
Domain snapshot 3sep2016u1 deleted

Verify it:
# virsh snapshot-list --domain openbsd
Name Creation Time State
------------------------------------------------------------

Now delete the vm:
# virsh undefine --domain openbsd
Domain openbsd has been undefined
# rm -f /nfswheel/kvm/openbsd.qcow2
