[Xen-devel] Performance isolation in Xen

[John L Griffin <jlg@xxxxxxxxxx>]

A few weeks ago I posted about my interest in developing "resource 
control" for Xen -- e.g., low-level mechanisms that could be used to 
provide QoS guarantees to partitions, by enforcing SLA-type policies on 
the resources (CPU, network, storage, etc.) consumed by each domain.

I've come up with a requirements/design document that describes the 
motivation for this work and my initial plan of attack.  The document is 
here:
http://www.ece.cmu.edu/~griffin2/xen/

As per the earlier discussion, it's not a simple problem, so I'm 
interested to hear any comments on the expected effectiveness of this 
proposed approach.  I'll update that page (and post updates here) as the 
work progresses.
