I am not sure what kind of cluster you used in your env, galera cluster 
for mysql or MariaDB galera cluster? how did you configure and start the 
galera cluster?
I set MariaDB galera cluster up successfully before. And here is my 
understanding on the notes:
After installed and configured,
1. Start the first node with galera_new_cluster, but the left nodes use 
service mysql start.
2. Turn on the firewall's ports accordingly on each node.
http://docs.openstack.org/ha-guide/shared-database-configure.html

For debug purpose, you can comment out the nodes in gcomm and change it 
to be "wsrep_cluster_address=gcomm://", then try to start it and the 
wsrep_cluster_size
should be 1 if successfully.
