Hi Carlos, If you're using shared storage across the nodes/hypervisors, the HostedEngine VM should already be HA. Sometimes this allows the engine to drop while restarting it on another node. Usually when this happens the rest of the nodes running VMs stay up, and things resync when the downed node comes back. IE the only one to lose pings is the Hosted-Engine. Unless ofcourse there were VM's on the same node, in which case, if they were HA VMs they will be restarted/resumed depending on your settings.

Anyone can help me to build HA on HostedEngine VM?
How can i guarantee that if host with HostedEngine VM goes down, the HostedEngine VM moves to another host?

Hello,
I have one cluster with two hosts with power management correctly configured and one virtual machine with HostedEngine over shared storage with FiberChannel.
When i shutdown the network of host with HostedEngine VM, it should be possible the HostedEngine VM migrate automatically to another host?
migrate on which network?
What is the expected behaviour on this HA scenario? After a few minutes your vm will be shutdown by the High Availability agent, as it can't see network, and started on another host.
I'm testing this scenario and after shutdown network, it should be expected that agent shutdown ha and started on another host, but after couple minutes nothing happens and on host with network we getting the following messages:
Aug 16 11:44:08 ied-blade11.install.eurotux.local ovirt-ha- agent[2779]: ovirt-ha-agent ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine.config ERROR Unable to get vm.conf from OVF_STORE, falling back to initial vm.conf
I think the HA agent its trying to get vm configuration but some how it can't get vm.conf to start VM.
