Re: [ovirt-users] Automatically migrate VM between hosts in the same cluster
Hi Alex
2) My question was: "what can I do, so that in case of Kernel
Panic or similar, the VM will be migrated (live or not) to another host?"
You would make the VMs HA and acquire a fencing solution.
What do you mean now? Have two VM and build a cluster? This is not what we want...
If it's possible, I'd like to have more Host AS CLUSTER with migration of the VM
between the nodes...
I think oVirt already do that, since I have to create Clusters. For me a Cluster is not
just "more nodes with the same CPU", but also something with load balancing or
high availability...
3) I'd like to have a shutdown-script on the host that put the
host in Maintenance and wait until it's done, so that I can just shutdown or reboot it
without any other action. Is it possible? It would help to manage the power
failure, too, assuming that other hosts have better UPS (it can be possible.)
You could probably use the REST API on the Ovirt Engine for that.But it might be better
to have a highly available machine (VM or not) running something like Nagios or Icinga
which would perform the monitoring of your
hosts and connect to the REST API to perform maintenance and shutdown. You might also
consider a UPS service like NUT (unless you're already doing it).
Well, I already use NUT and we have Icinga monitoring the hosts.
But I can't understand what you mean and (more important!) how can I do it...
I checked the REST API and the CLI. I can write a little script to put an host in
Maintenance or active it again, that's not the problem.
The problem is to have somewhat starting this script automatically...
Any suggestion? Icinga will not be the solution, since it checks the host every 5 minutes
or so, but we need to have this script started in seconds...
Thanks
Mit freundlichen Grüßen
