I upgraded to 3.3.0-4 (latest) oVirt and tried snapshot:

(newly created VM):

Snapshot 'test' creation for VM 'server1.testlab.org' was initiated by 
admin.
Failed to create live snapshot 'test' for VM 'server1.testlab.org'. VM 
restart is recommended.
Snapshot 'test' creation for VM 'server1.testlab.org' has been completed.
I can see newly created snapshot in oVirt GUI.

(imported VM):
Snapshot 'test2' creation for VM 'server2.testlab.org' was initiated by 
admin.
Failed to create live snapshot 'test2' for VM 'server2.testlab.org'. VM 
restart is recommended.
Snapshot 'test2' creation for VM 'server2.testlab.org' has been completed.
I can see newly created snapshot in oVirt GUI.

The clone function works as expected (created ew VM from snapshot).
