[Pacemaker] Multicast pitfalls? corosync [TOTEM ] Retransmit List:

[Beo Banks]

hi thanks...for your help.

i have two node cluster
both node are running on seperate hosts.

the 2x hosts have 2 nic's ....eth0 is 172.XXX...whatever and eth1 is
direct connection (crossover cable) between the hosts.

the issue must be my kvm host,or?
