Hello,

i've 2 machines, running ubuntu 12.04, i've installed corosync + pacemaker and it was working fine.

Corosync is using eth1 with 10.8.0.1 and 10.8.0.2 as ip of the hosts, i've got keystone, glance, nova api-cert-scheduler, mysql, rabbitmq working in HA with pacemaker.

The problem comes after installing nova-network and nova-compute, i've used this nova.conf:

http://pastie.org/private/ddwva8kvaypqrxk7rifvba

and after nova-compute started and hosts rebooted i can't get to work corosync,

the problem seems that when hosts send packets in eth1 to multicast address, the source ip is the public one, not the 10.8.0.x one. After disabling nova-network on boot everything works.

I've also tried to create a virtual eth2 device and set flat_interface to eth2, but it seems that still nova-network break the configuration as corosync still uses public ip for private lan.

Any idea?

Best Regards
