Automatic live migration feature for KVM

[Wido den Hollander]

Hi,

RHEV and VMWare have features which automatically migrate VMs away from 
very busy hosts to prevent noisy neighbors.

VMware calls this DRS (Distributed Resource Scheduler) where it keeps 
migrating virtual machines to balance the workload over different hosts.

I wonder if somebody knows if something like this is available for KVM 
with CloudStack or if somebody has ever put effort into this.

Thanks,

Wido
