[ovirt-users] HA not working 3.4.2

Hi i was testing HA of ovirt,(i am from Xenserver background and trying to use KVM solution in our environment) Have 2 hosts with NFS storage and i tested migration between these two hosts. On Host2 while VM was running on it, i unplugged Power cable and it took long minutes to update that VM is down,okkk now long wait...... .. ..... ....... VM state changed to *unkown *and not booted on second Node ie Host1 its been half an hour and still the VM is not restarted What can be the issue?What should i do it make the VM in real HA so that it will be restarted on the active node. *How HA is enabled* what i did was while creating vm> Advanced option>High Availability>Highly Available I am sure this can be a configuration error,Can some one please help me with enabling HA. Please Help Thanks
