Thanks, guess this is entering the realm of scheduling & group scheduling and how "just the right" level of information is needed to do efficient group scheduling in nova/ironic vs the new/upcoming gantt service. To me splitting it into N single requests isn't group scheduling but is just more

Doesn't nova already have logic for creating N virtual machines (similar to a group) in the same request? I thought it did (maybe it doesn't anymore in the v3 API), creating N bare metal machines seems like it would comply to that api? Sent from my really tiny device... > On Jan 22, 2014, at 4:
