Hi,

to achieve Active - Active Disaster Recovery , if my three hosts in DC power Down or
Failed my DR Site Three node should take care of running virtual machines.
During Split-brain scenario Ovirt-Hosted-Engine VM goes in PAUSE mode and not restarting
on DR hosts and waited for long time, due to this my all production VMs are not restarting
on DR Site.
please guide to achieve Active-Active Disaster Recovery with 6 node stretched cluster. i
referred document hosted official site but did not get success, it would be great help of
