[Pacemaker] Configuring Pacemaker & DRBD

[Cliff Massey]

I  meant 8.40 :)

 I ended up deciding to use Corosync instead of Heartbeat and it is working now. Now I'm configuring a KVM resource to depend on drbd. The KVM machine is started by Pacemaker,  but when I try "resource migrate" to move it to the other node nothing happens.

I've posted my CIB dump at patstebin: http://pastebin.com/EgLxRS0c and the log messages are http://pastebin.com/7f18RqHc
