Open Stack

Hi all,

So I've proposed a Forum session to discuss some of these issues and
use-cases: http://forumtopics.openstack.org/cfp/details/124 - there
would seem to be value in getting Nova, Blazar and OPIE folks together
to talk about advanced scheduling use-cases. In particular it looks
like there is a need (and gap?) for Nova's scheduler to model and
support (either directly or through extension/pluggability) more than
just on-demand scheduling workflows.

However, I'm not an active dev and am somewhat ignorant on the state
of nova-scheduler and related components now, so would appreciate
someone who knows what they are talking about to help chair this
session and provide some updates to the proposal that include
background reading etc.

Cheers,
