Hi Honza,
Multicast is working. I tried with ssmping. ping is working as well with new entries in /etc/host (pcmk-1 and pcmk-2 are able to ping). Applying your advices, crm_mon hangs with "Attempting connection to the cluster........................." There is no firewall rule. Openvz vps. Logs are kept empty. I don't know what is going wrong there.. Any clue ?
