Hi,
This is regarding HA VM fail to restart on other host.
I have setup, which has 2 host in a cluster let say host1 and host2.

And also not storage domain is configure on host3 and it available all
time.

Can anyone explain about this behaviour ? Or Is this an issue ?
Note : I am using Ovirt 4.0.

Hi,
If a host is powered off and if powermanagment is enabled engine
will fence the host and restarts it. During this process host residing
on the vm will be shutdown and will be restarted on another node. All
the events can be seen in the engine UI.
Hope you have not missed to enable power management on the hosts.
with out enabling power management even if the vm is marked to be Highly
available it will not be.
Second thing to check for is if the vm has guest-agent installed on
it. If the vm does not have guest-agent installed then it wont be
restarted on different host. More info on this can be found at [1].
