Re: [Xen-devel] [PATCH] Scheduling groups, credit scheduler support



My interpretation of your implementation is that it causes hierarchal relationships (master/slave) between domains. Every group has one master and the rest are slaves. The fixed relationships puts implicit limits on the organization of domains. (See http:// www.hpl.hp.com/techreports/94/HPL-94-104.html, for example)

Since groups are applicable to more than just scheduling (domain disaggregation, convenient migration, efficient security policy, etc.), a more general mechanism would be preferable.

I submitted something similar in the past (Feb 20, 2007). If anyone is interested, I'd be glad to submit a fresh cut of my patches as an RFC.
