Bug Description

If using nova with neutron and you run the following command:

nova boot --image cirros-0.3.1-x86_64-uec --flavor 1 --nic net-id=41b95a61-c052-4cfa-8361-493e8d7298e3 --nic net-id=4658b15d-1a0c-4a13-bd28-b5dd41b5feee --nic net-id=70da3b11-531c-471c-89cb-8146183c5470 --flavor 100 vmx --num-instances 30

and you do not have enough quota it would be nice if nova-api would raise an error or perhaps actually try and launch 30 instances. Instead you get some number of instances up to your port-quota.

This is a novaclient bug, the nova API has min_count and max_count. if min_count is over the quota limit the command will fail. So novaclient should be updated to support min_count and max_count flags and deprecate num-instances (as an alias for max count)

    Deprecate num-instances in favor of min/max count

    For 'nova boot', num_instances only set max_count, which will try to
    launch up to max_count instances. But sometimes users want to either
    launch min_count instances or nothing. So deprecate --num-instances
    and use --min-count and --max-count instead.

    DocImpact: deprecate '--num-instances' for 'nova boot'
