I was, in fact, investigating a CKRM port in this regard. The idea, as
you said, would be to have a live pool of VMs. Given the transparencey
of migration, and the ease of dynamic management of VMs, we'd like to
"virtualize" the whole cluster so that multiple users can have their
own "virtual clusters" for their experiments. But we want to be able
to really fine tune the allocation and management of various
resources. CKRM looks to be a good first step, though I believe it can
be done using existing Xen features (like the atropos scheduler)
