I agree it's a lot to get through,  but we're working to a budget of only 3 slots for scheduler sessions.   If we split this across two slots as originally suggested by Gary, then we don't get to discuss one of "generalized metrics/ceilometer"  or "performance" at all - which would seem an even worse compromise to me.

We never going to be able to avoid session which have more content than can comfortably fit into a single slot - that's kind of just a way of life from the time constraints of the summit - what we're trying to do is make sure that we can plan those sessions ahead of time rather that the morning before at the Hotel ;-)

I did add a rider that if Russell can give a 4th session to scheduling then this is the one that would most benefit from being split.

Hi Phil

Good summary ...

I was wondering if we are shooting for too much to discuss by clubbing
 i) Group Scheduling / Smart Placement / Heat and Scheduling  (1), (2), (3), & (7)
        - How do you schedule something more complex that a single VM ?

I think specifying something more complex than a single VM is a great theme. But dont know if we can do justice in 1 session. I think maybe a simple nova scheduling API with groups/bundles of resources  itself would be a lot for 1 session. In fact in order to specify what you want in your resources bundle, you would need to think about policies.
So maybe just the simple Nova API and policies might be useful.

Also we might have a session correlating the different models of how more than 1 VM can be requested - you could start from nova and then generalize to cross services or you could start from heat workload models and drill down. There are passionate people on both sides and maybe that debate needs a session.

I think the smart resource placement is very interesting and might need at least 1/2 a slot since one can show how it can be done today in nova and how it can handle cross services scenarios.

See you tomorrow on IRC
