hi,

yes, it is possbile to solve that problem. But it is a little bit tricky and 
you need to play with the XML config file. No shell (pcs, crm) I would know of 
supports that feature.

For details see:

http://clusterlabs.org/doc/en-US/Pacemaker/1.1-
crmsh/html/Pacemaker_Explained/_using_rules_to_control_resource_options.html

The example given uses different ports on the cluster nodes, but it also works 
for different interface names on the nodes.

ON the other hand, you could the resource figure out the interface by itself 
via the routing lookup. If the nodes have a dedicated IP address in the net of 
the VIP it should work automagically.
