[Openstack] cgroups cpu share allocation in grizzly seems incorrect

I sent this to the openstack-dev list but got no response, so I'll repost here. In Grizzly regardless of the number of vCPUs the value of /sys/fs/cgroup/cpu/libvirt/qemu/instance-X/cpu.shares seems to be the same. If we were overloaded, this would give all instances the same cpu time regardl

[Openstack] object-oriented design in nova--room for improvement?

Hi, I'm pretty new to OpenStack, so maybe I'm still not grokking the overall design. Feel free to tell me I'm totally full of it. :) Anyways, I've been poking around in the code with an eye towards maybe extending the set of information exported by the compute nodes for use in scheduler fi
