Description camorris@redhat.co 2022-05-05 19:40:40 UTC 
Description of problem:
The problem exists only when we use OpenShift to create new instances. Creating new instances using OpenStack UI works fine.

The problem exists only for our prod and preprod clusters. Our dev OpenShift 4.8 clusters, running on the same OpenStack instance (just different project) can scale as expected.

This was investigated by both OpenShift admin and OpenStack admin from our side. We didn't find anything interesting in the OpenStack logs and the OpenShift logs are not very helpful. The volume is definitely created. We also made sure there are no quota constraints that could block creation of the instance or other resources.

Version-Release number of selected component (if applicable):
OpenShift 4.8
Red Hat OpenStack Platform release 16.1.6 GA (Train)

How reproducible:
Everytime

Steps to Reproduce:
1. time OS_CLOUD=overcloud openstack port list --project f495c8f1d1824bb3891d72e095bd66cd
real    0m49.534s

Actual results:
Too slow, causing instances creation to time out

Expected results:
Not timeout
