Hi,
Your guest-vm have to be defined as " Highly Available"
Highly Available
Select this check box if the virtual machine is to be highly available. For example, in
cases of host maintenance or failure, the virtual machine is automatically moved to or
re-launched on another host. If the host is manually shut down by the system
administrator, the virtual machine is not automatically moved to another host.
Note that this option is unavailable if the Migration Options setting in the Hosts tab is
set to either Allow manual migration only or No migration . For a virtual machine to be
highly available, it must be possible for the Manager to migrate the virtual machine to
other available hosts as necessary.
Thanks in advance.
Best regards,
Nikolai

Thanks for detailed explanation. Do you mean only HE VM can be failover? I want to have a
try with the VM on any host to check whether VM can be failover to other host
automatically like VMware or Xenserver?
I will have a try as you advised and provide the log for your further advice.
Thanks,
Cong

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,

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

Subject: [ov=
irt-users] VM failover with
ovirt3.5<br>><br>><br>><br>>
Hi<br>=
><br>><br>><br>> In my environment, I have 3
ovirt nodes as one=
cluster. And on top of<br>> host-1, there is one vm to host ovirt engin=
e.<br>><br>> Also I have one external storage for the cluster to
use =
as data domain<br>> of engine and data.<br>><br>> I
confirmed live=
migration works well in my environment.<br>><br>> But it seems
very =
buggy for VM failover if I try to force to shut down<br>> one ovirt node=
. Sometimes the VM in the node which is shutdown can<br>> migrate to oth=
er host, but it take more than several minutes.<br>><br>>
Sometimes, =
it can not migrate at all. Sometimes, only when the host is<br>> back, t=
he VM is beginning to move.<br>><br>> Can you please check or
share t=
he logs under /var/log/ovirt-hosted-engine-ha/<br>>
?<br>><br>> Is=
there some documentation to explain how VM failover is working? And<br>>=
; is there some bugs reported related with this?<br>><br>>
