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?
it's in charge of ovirt-ha-agent running on your hosts.
Can you please post the output of hosted-engine --vm-status ?
There is the output of both hosts: [root@ied-blade11 ~]# hosted-engine --vm-status /usr/lib/python2.7/site- packages/ovirt_hosted_engine_ha/lib/storage_backends.py:15: DeprecationWarning: vdscli uses xmlrpc. since ovirt 3.6 xmlrpc is deprecated, please use vdsm.jsonrpcvdscli import vdsm.vdscli --== Host 1 status ==-- Status up-to-date : True Hostname : ied-blade13.install.eurotux.local Host ID : 1 Engine status : {"health": "good", "vm": "up", "detail": "up"} Score : 3400 stopped : False Local maintenance : False crc32 : a941698e Host timestamp : 153049 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=153049 (Thu Aug 18 09:22:02 2016) host-id=1 score=3400 maintenance=False state=EngineUp stopped=False --== Host 2 status ==-- Status up-to-date : True Hostname : ied-blade11.install.eurotux.local Host ID : 2 Engine status : {"reason": "vm not running on this host", "health": "bad", "vm": "down", "detail": "unknown"} Score : 3400 stopped : False Local maintenance : False crc32 : 8f79e0e7 Host timestamp : 143139 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=143139 (Thu Aug 18 09:22:12 2016) host-id=2 score=3400 maintenance=False state=EngineDown stopped=False [root@ied-blade13 ~]# hosted-engine --vm-status /usr/lib/python2.7/site- packages/ovirt_hosted_engine_ha/lib/storage_backends.py:15: DeprecationWarning: vdscli uses xmlrpc. since ovirt 3.6 xmlrpc is deprecated, please use vdsm.jsonrpcvdscli import vdsm.vdscli --== Host 1 status ==-- Status up-to-date : True Hostname : ied-blade13.install.eurotux.local Host ID : 1 Engine status : {"health": "good", "vm": "up", "detail": "up"} Score : 3400 stopped : False Local maintenance : False crc32 : cdd022a2 Host timestamp : 153085 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=153085 (Thu Aug 18 09:22:38 2016) host-id=1 score=3400 maintenance=False state=EngineUp stopped=False --== Host 2 status ==-- Status up-to-date : True Hostname : ied-blade11.install.eurotux.local Host ID : 2 Engine status : {"reason": "vm not running on this host", "health": "bad", "vm": "down", "detail": "unknown"} Score : 3400 stopped : False Local maintenance : False crc32 : fbbad961 Host timestamp : 143175 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=143175 (Thu Aug 18 09:22:48 2016) host-id=2 score=3400 maintenance=False state=EngineDown stopped=False

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.
