Please shutdown all VMs in the Cluster.” According tohttps://bugzilla.redhat.com/show_bug.cgi?id=1341023 <https://bugzilla.redhat.com/show_bug.cgi?id=1341023> this should be fixed in 3.6.7. Any ideas?

this bug is blocking it, later bugs 
(linked from there) allows it, though there are other issues…so if you have an option to shut them down please do so.
note those are RHEV bugs, not oVirt bugs so the exact build may differ
