They(VMs) are deleted. So, my situation is this: I have clean install of ovirt 3.3.0beta with imported VMs from export domain. Everything works except snapshots. But when I restart ovirt mgmt server, VMs will disappear. Right now I am doing hourly backup of DB.

I can not use workaround with converting domain to export domain, because we use iscsi. It would be perfect if I can retake existing domain. Another gap is if I dont detach export domain I can not attach it to new datacenter and I have to manually edit some files. It would be absolutely perfect to do it from ovirt web gui (for example by "force override button")
