[ovirt-users] VM failover with ovirt3.5

Yue, Cong Cong_Yue at alliedtelesis.com
Mon Dec 29 18:29:04 UTC 2014


I disabled local maintenance mode for all hosts, and then only set the host where HE VM is there to local maintenance mode. The logs are as follows. During the migration of HE VM , it shows some fatal error happen. By the way, also HE VM can not work with live migration. Instead, other VMs can do live migration.

I see that HE vm run on host with ip 10.0.0.94, and two another hosts in "Local Maintenance" state, so vm will not migrate to any of them, can you try disable local maintenance on all hosts in HE environment and after enable "local maintenance" on host where HE vm run, and provide also output of hosted-engine --vm-status.
Failover works in next way:
1) if host where run HE vm have score less by 800 that some other host in HE environment, HE vm will migrate on host with best score
2) if something happen to vm(kernel panic, crash of service...), agent will restart HE vm on another host in HE environment with positive score
3) if put to local maintenance host with HE vm, vm will migrate to another host with positive score
Thanks.

Could you please explain how VM failover works inside ovirt? Is there any other debug option I can enable to check the problem?

Thanks,

I see that you set local maintenance on host3 that do not have engine vm on it, so it nothing to migrate from this host.
If you set local maintenance on host1, vm must migrate to another host with positive score.

Subject: Re: [ovirt-users] VM failover with ovirt3.5

Hi

I had a try with "hosted-engine --set-maintence --mode=local" on
compute2-1, which is host 3 in my cluster. From the log, it shows
maintence mode is dectected, but migration does not happen.

The logs are as follows. Is there any other config I need to check?

Subject: RE: [ovirt-users] VM failover with ovirt3.5

Thanks for the information. This is the log for my three ovirt nodes.
From the output of hosted-engine --vm-status, it shows the engine state for
my 2nd and 3rd ovirt node is DOWN.
Is this the reason why VM failover not work in my environment?

No, they looks ok: you can run the engine VM on single host at a time.

How can I make
also engine works for my 2nd and 3rd ovit nodes?

If you put the host 1 in local maintenance mode ( hosted-engine --set-maintenance --mode=local ) the VM should migrate to host 2; if you reactivate host 1 ( hosted-engine --set-maintenance --mode=none ) and put host 2 in local maintenance mode the VM should migrate again.

Can you please try that and post the logs if something is going bad?

Subject: [ovirt-users] VM failover with ovirt3.5



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?

http://www.ovirt.org/Features/Self_Hosted_Engine#Agent_State_Diagram

Thanks in advance,

Cong
