Re: [Openstack] Potential filter scheduler enhancement

2013-01-03 Thread Joseph Suh
Phil, I agree with the suggestion. We wanted to instantiate a set of VMs whose hosts are located close each other. The current scheduler could not handle this use case since it needed to return optimal set of hosts at the same time. The first optimal host returned by the current scheduler may
