[ovirt-users] Ovirt-Engine HA

Hi Ovirt Users, Do you have any documentation, tutorial, howto or workaround to perform or to have an ovirt-engine HA? Iv'e tried to google about this but I can't find any. let's say I want to have two engine, engine1 is currently managing two hypervisor, then engin2 is my reserved engine, so I can still managed those vm that are running inside of my hypervisor if ever engine1 fails. TIA :) Sandvik
