[ovirt-users] Query on High Availability of VMs

Mon May 23 09:08:29 UTC 2016

Now I did shutdown the VM and then made changes to watchdog and can see that the settings are retained now…But the VM is shut down immediately after the host is offline but does not restart!!! The guest machine is running on centos 6.7 OS.

I can see below messages in the engine.log

Thanks a lot for the reply.
Actually I had set the watchdog daemon to i6300esb  and reset.
But then When I press ok , I get a message saying the VM has been updated.
But when I recheck again the settings revert back to watchdog model to “No watch dog” Its  weird..

Thanks
Geetha

The vms are controlled by watchdog daemon. in your last screenshot the watchdog operation is not defined.You should select between reset/pause or stop.
Hi All,

I am Geetha here. I am trying to test High availability of VMs in Ovirt.
The setup is I have two hosts. Power Management is configured using ilom (ilom ports).

[cid:image001.png at 01D1B4DA.546A2E10]

The Vms are configured to be high available as below

[cid:image002.png at 01D1B4DA.546A2E10]

Cluster Policy allows Vm migration

Now in this scenario, When I take the hosts to maintenance mode , All the VMS automatically migrate to another hosts which is great.

But when one of the hosts goes offline the VMs just shuts down and does not restart on another hosts.

Is there any configuration I am missing?

Can anyone help me please?

Thanks
Geetha
