Hello, On my icehouse installation I can see when deploying 9VMs through a heat pattern, only 4 VMs are spinning up at once. Is there a way to tune this to have alle 9VMs spinning up at once?

Thank you very much.

UPDATE: Is the parallel deployment in Nova dependant on how many osapi_compute_workers I have? Found this entry in the nova.conf documentation.

osapi_compute_workers = None (IntOpt) Number of workers for OpenStack API service. The default will be the number of CPUs available.

So If I have 5 nova-api processes running on my machine I can deploy up to 5 instances in parallel?

Icehouse, seriously?

AFAIR Heat was fully parallel by that point, so it's likely the limit is in your Nova configuration (I thought the default limit was 10, but I may be misremembering).

Thanks for your response. Do you know if this nova limit can be changed in some way? or where I can see what is the limit right now?
