[ovirt-users] Before migrating to Ovirt

Hello Ovirt users, Currently we haveing 4 Xen pools in our organization each pool have 8 servers. Due to new 7.3 version change ,we plan to migrate our upcoming 5th pool to Ovirt, the decision to do POC migration to Ovirt is from lots of Xen users that suggested Ovirt migration better and mature product migrate to it. I started to test Ovirt currently only with one server with engine installed, my question regarding Ovirt sine i am really newbie with that system , is , is it possible to have multiple engine on it ? What happen if the engine server crash with some reason? can i load it on another cluster server? Please advice Thanks -- Tal Bar-or
