My problem is that I need to have rabbitmq running on both node1 and node2.I
also need the IP to fail over if rabbitmq were to fail on the current node.
The 2 rabbitmq services are communicating with each other. Data is pushed to
the clients.
Even though the IP may currently live on node1, data may flow through node1
then through node2 (via rabbit) and out to client.
Rnode1 -------> client1 /
/|\DB---->VIP | \|/
Rnode2 --------> client2
Maybe I should not have these resources grouped together since that implies
collocation infinity for IP and rabbitmq?

'migrate' has special meaning here.
After a failure rabbitmq is moved (stopped on the old node and started on the
new one), which is different from a migration.
Leaving rabbitmq in an unclean state on node1 would definitely not be a good
idea.
