Hi, So, if I paraphrase correctly what is meant out of the stacker jargon. min_count and max_count doc will go in the API doc as an extension item once the DisableServerExtension cleanup is done. Right?
However, the original question was about the *num_instances* property of the RPC request spec. I do not see a direct relationship with min_count and max_count. So, is num_instances another undocumented API extension parameter or something else? I can see also that DisableServerExtensions proposal mentions a *reservation_id *parameter... Can someone explain what it is ? Is it to support server reservation like in AWS EC2? And so, would a user be able to create a reservation (that is, not to actually create the reserve servers but to reserve the) with say additional min_count max_count parameters in the request. The reservation would fail if min_count cannot be honored by OpenStack. If the reservation can be honored, would return a reservation_id along with a value between min_count and max_count. Is this a correct understanding of the behavior or complete speculation?
