[ovirt-users] disk not bootable

Nir,
I found something very interesting.
When exporting the same vms and templates and than importing them to a
new cluster running ovirt 4.0 that has iSCSI mounts ONLY, they import
and run just fine. I notice that the disk imported as Blank templates
and they do not seem to have any dependency to the templates. Is this
normal behavior?
