[ovirt-users] VM failover with ovirt3.5

I collected the agent.log and vdsm.log in 2 cases.
Case1 HE VM failover trail
What I did
1, make all host be engine up
2, set host1 be with local maintenance mode. In host1, there is HE VM.
3, Then HE VM is trying to migrate, but finally it fails. This can be found from agent.log_hosted_engine_1
As for the log is very large, I uploaded into google dirve. The link is as
https://drive.google.com/drive/#folders/0B9Pi5vvimKTdNU82bWVpZDhDQmM/0B9Pi5vvimKTdRGJhUXUwejNGRHc
The logs are for 3 hosts in my environment.
Case2 non-HE VM failover trail
1, make all host be engine up
2,set host2 be with local maintenance mode. In host3, there is one vm with ha enabled. Also for the cluster, "Enable HA reservation" and Resilience policy is set as "migrating virtual machines"
3,But the vm on the top of host3 does not migrate at all.
The logs are uploaded to good drive as
https://drive.google.com/drive/#folders/0B9Pi5vvimKTdNU82bWVpZDhDQmM/0B9Pi5vvimKTdd3MzTXZBbmxpNmc
Thanks,
Cong

Can you provide vdsm logs:
1) for HE vm case
2) for not HE vm case
Thanks

Thanks for the advice. I applied the patch for clientIF.py as
- port = config.getint('addresses', 'management_port')
+ port = config.get('addresses', 'management_port')
Now there is no fatal error in beam.log, also migration can start to happen when I set the host where HE VM is to be local maintenance mode. But it finally fail with the following log. Also HE VM can not be done with live migration in my environment.

Besides, I had a try for other VMs instead of HE VM, but the failover( also no start to try migrating) happen. I set HA for those VMs. Is there some log I can check for this?
Please kindly advise.
Thanks,

>>
>> Hi
>>
>>
>>
>> In my environment, I have 3 ovirt nodes as one cluster. And on top of
>> host-1, there is one vm to host ovirt engine.
>>
>> Also I have one external storage for the cluster to use as data domain
>> of engine and data.
>>
>> I confirmed live migration works well in my environment.
>>
>> But it seems very buggy for VM failover if I try to force to shut down
>> one ovirt node. Sometimes the VM in the node which is shutdown can
>> migrate to other host, but it take more than several minutes.
>>
>> Sometimes, it can not migrate at all. Sometimes, only when the host is
>> back, the VM is beginning to move.
>>
>> Can you please check or share the logs under
>> /var/log/ovirt-hosted-engine-ha/
>> ?
>>
>> Is there some documentation to explain how VM failover is working? And
>> is there some bugs reported related with this?
