No. But this is actually not needed at all. What you want is a Xen block script that switches the primary/secondary mode at the right time. (That is probably not feasible with pacemaker managing the DRBD instance.) With each DRBD instance dedicated to a single VM, that ought to work fine. The VM never actually accesses the block storage from both nodes concurrently. There shouldn't be a need for dual-primary headaches here. The script should not be too hard; you can likely look at block-dmmd and model on that.
