In the documentation of
http://www.ovirt.org/OVirt_Administration_Guide#.E2.81.A0Improving_Uptime_with_Virtual_Machine_High_Availability
it says
To enable the migration of highly available virtual machines:
Power management must be configured for the hosts running the highly available virtual machines.
Does this mean I need to confirgure all poer management for all ovirt nodes?
Thanks,
Cong

Subject: RE: [ovirt-users] VM failover with ovirt3.5
Thanks for the information. This is the log for my three ovirt nodes.
From the output of hosted-engine --vm-status, it shows the engine state for my 2nd and 3rd ovirt node is DOWN.
Is this the reason why VM failover not work in my environment? How can I make also engine works for my 2nd and 3rd ovit nodes?
