Grigori, Corosync configuration files you've send looks good. I believe problem is really in your configuration of firewall in guest or host OR VM bridge misconfiguration. So my recommended actions: - Stop firewall on all guests and host (+ try exec) if not helps - What bridge are you using? NAT will not work. Bridged Adapter or Host-only adapter mode should work. I'm really unsure about internal network (but I believe this also works).
