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



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.
