Hi, For live migration use PV DomUs and Xen's drbd block script - it automatically switches primary/secondary states on both domUs while migrating.
Anyway yes, its that simple - two primaries and live migration works. Note: I've been having some issues (crashes) with centos xen kernel and drbd 8.3.10 - don't have the time to investigate further.
