Nir, exactly! Different data center (physical) - As I said, in addition to limitations of network connections and latency, different subnets/vlans and different storage technologies. In this case, one suggestion would be to allow Live Storage Migrate through the management interface (ovirtmgmt), assuming that there is routing/connection between data centers managed by the same Engine/Manager - the storage domain layer would be abstracted at that point, but it would be allowed to copy a disk between different storage domains, in different physical/logical data centers. At the end of the process, a pause could be made on the VM for the process to be successfully terminated and there is no data interruption/corruption. I don't know if I'm being clear. it would only be a suggestion for this to be implemented, because currently XenServer/XCP and VMWare are able to perform this type of migration. It is an important feature and that many users miss when they migrate to the Virt.
