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")
