Good to hear!
Just remember Remus is FT (Fault Tolerance) solution..
often it's better use software/service based HA instead of vm-based FT.
FT is way slower than "normal" HA.

Can you elaborate a bit, both re. what you see as the difference between fault tolerance vs. HA, and re. speed?

Currently, I'm running a collection of services on a single VM, with DRBD/heartbeat/pacemaker failover to a 2nd node. Failover takes a LONG time. Looks to me like Remus should provide instant failover.
