Bug 1251571

Description of problem:

A small overcloud deployment that follows our recommendations for configuring network irolation (6 networks) exceeds default neutron port settings.

Version-Release number of selected component (if applicable):
python-rdomanager-oscplugin-0.0.8-44.el7ost.noarch

How reproducible:

Steps to Reproduce:
1. Deploy undercloud
2. Configure network iso with 6 recommended VLANs
3. Deploy overcloud of 11 or more physical servers

Example:

openstack overcloud deploy -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml -e /home/stack/network-environment.yaml --control-flavor control --compute-flavor compute --ceph-storage-flavor ceph --ntp-server 10.16.255.2 --control-scale 3 --compute-scale 4 --ceph-storage-scale 4 --block-storage-scale 0 --swift-storage-scale 0 -t 90 --templates -e /usr/share/openstack-tripleo-heat-templates/environments/storage-environment.yaml

Actual results:

overcloud deploy command fails with errors:

ResourceUnknownStatus: Resource failed - Unknown status FAILED due to "Resource CREATE failed: ResourceUnknownStatus: Resource failed - Unknown status FAILED due to "Resource CREATE failed: ResourceUnknownStatus: Resource failed - Unknown status FAILED due to "Resource CREATE failed: OverQuotaClient: Quota exceeded for resources: ['port']"""

Expected results:

Workaround:

Prior to depoying overcloud:

[stack@rhos0 ~]$ neutron quota-update --port 100
