Re: [Xen-users] Cluster Xen with real load balanced between more machine

["Nick Couchman" <Nick.Couchman@xxxxxxxxx>]

In order to do this you need to use some sort of cluster management software, 
like Heartbeat, to manage the resources automatically.  It is not possible for 
a domU (Xen virtual machines) to take advantage of resources (CPU, network, 
memory) on more than one physical machine at a time.  What you can do, though, 
is use some sort of load balancer software combined with Xen's built-in live 
migration to migrate VMs from one host to another as load increases or 
decreases on a particular server.  In this way, you can make sure that the load 
is balanced across all of your physical servers.
