And I just spotted that KVM supports migration 
(http://kvm.qumranet.com/kvmwiki/Migration) and is integrated in the 
2.6.21 kernel.

This would allow the scheduler to schedule on the actual resources being 
used by an application and suspend and/or migrate a job whenever 
necessary. Would'nt such an approach be far more superior (in terms of 
throughput) and much easier to use ?
