In oVirt 4.1 we are planning to allow VM leases that will allow you to restart HA VMs in this use case even without power management.
We would love some feedback on this on the latest tested build, if you want to try it out:

Hi,

high availability requires power management to be configured properly for your hosts. The VM won't be restarted until we can ascertain the status of node2 (because it can still be up).

The host is Non responsive, meaning we do not know if it is up or down. That is the reason we show the VM status as unknown.

You can fix that by configuring power management for node2 or by right clicking and selecting Confirm host has been rebooted menu option.

Hi, all
        I have an ovirt 4.0 environment with two hosts and a hosted engine. The engine vm was running on host 1 and another vm was running on host2. Then I unpluged the power of host 2. The another vm should be supposed to restart on host 1 because of ha feature. But it couldn't. It stayed unknown status all the time. And the host 2 stayed non responsive status.

        Did I understand ha correctly? Anyon can help? Thanks!
