I sent this to the openstack-dev list but got no response, so I'll
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 regardless of the number of vCPUs in the instance.
Is this design intent? It seems to me that it would be more correct to
have the instance value be multiplied by the number of vCPUs.
