Be careful with your load-balancing Ivan - Since CloudStack relies on MySQL’s GET_LOCK and RELEASE LOCK, multi-master isn't supported.

A person asked me whether i have experience of deploying ACS 4.9 with Galera HA cluster and after I answered - "I don't" I decided to try because I was unable to find relevant new article I wrote it as well. It explains how to deploy ACS 4.9.2 to Galera in CentOS 7. I published it under Apache License, so If someone includes it in docs it would be great, please also don't hesitate notifying me with any bugs found and considerations. Hope it'll help to someone.
