We are currently running OpenNebula 3.2 with external multi-master
mysql database, and heartbeat failover between the two controllers.
I believe there are some state issues to making them both active
via LVS or similar.
Also, even in heartbeat(active-passive), if the system fails over in the
middle of a onevm start, that operation won't be retried.

I know OpenNebula server isn't an essential piece for the cloud life: in
case of failure of OpenNebula server the VM still up and running.
But now I'm the situation of making some tests setup for OpenNebula
Colud Controller in HA, just to research.
I already tested a setup of 2 cloud controllers in HA with HeartBeat
without any problems, but I want to try a step over: do you known if
it's possible to configure 2 active nodes with OpenNebula? Obviously
using a MySQL datastore instead of SQLite to permit multiple concurrent
access.
Thanks,
Alberto Zuin
