Actually I was more interested in letting Xen do a class based
resource allocation among the various domains. AFAIK right now this is
crudely possible (by using the atropos CPU scheduler, some kind of
traffic shaping and/or rate based firewall at the domain0 network
interfaces and static disk partitioning (or dynamic using LVM)).
However, CKRM will allow a uniform infrastructure to handle all kinds
of resources in an integrated fashion.
