Description Neal Gompa 2016-04-13 14:50:22 UTC

Description of problem:
In oVirt, there does not appear to be a mechanism for moving virtual machines across data centers that use local storage, even if non-live migration is an option.

However, libvirt seems to expose this capability[1][2].

VMware's product has the capability, calling it "Storage vMotion" and supporting live migrations across heterogeneous storage types, disparate data centers and long distances, among other things[3].

It'd be very useful, especially as all-in-one setups go away in favor of hosted engine with 4.0.0 and in scenarios where it's not feasible to make shared storage fast enough to be useful for the workloads, but the HA property of live migration is still desired.
