Thanks, though got no FW between VM nodes, and multicast should be working too:

[root at afnA ~]# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

also corosync should be okay ImHO:

[root at afnA ~]# corosync-quorumtool  -l

   1   afnA.mxi.tdcfoo
   2   afnB.mxi.tdcfoo
