Re: [Linux-cluster] KVM availability groups


I am not an expert in this, but as far as i understand it works like this

There are vcenter-like interfaces, but I'm not sure how they handle HA, have a 
look at ganeti and/or openstack

this list is rather more concerned about the low level workings of clustered 
systems, with tools such as cman or pacemaker (depending on your OS version, I 
think all current RHEL versions use cman) to monitor and manage availability 
of your services (a VM is a service in this context), and corosync to keep 
your cluster in a consistent state.

if you are looking for a vsphere replacement, you might have better luck with 
openstack than tinkering with linux clustering directly, in my opinion.

You would probably use libvirt interface to manipulate with your KVM instances
