Now, the shared storage can be based on a DRBD Primary, and you can have it fail over to a DRBD Secondary, but dual primary is not going to do what you want and shared storage will. The storage you share may be virtualized, if you like.

Well, no - actually dual-primary is an elegant way to achieve live
migration without shared storage.

But it's much harder to get right, from everything I've read here and
elsewhere.
