Description smooney 2022-05-13 16:25:17 UTC 
This bug was initially created as a copy of Bug #2085517

I am copying this bug because: 



Description of problem: Unable to resize a stopped VM with latest phase3 puddle RHOS-17.0-RHEL-9-20220511.n.1, this is the first puddle this has happened for 17 and was previously passing. Also this test is failing across a couple of jobs [1,2].  Example build failure and logs here [3,4].  Failure logs attached as well.

Version-Release number of selected component (if applicable):
RHOS-17.0-RHEL-9-20220511.n.1

How reproducible:
First time seeing this for 17 with latest puddle, happened across several jobs.

Steps to Reproduce:
1. Deploy environment with RHOS-17.0-RHEL-9-20220511.n.1 and execute tempest test tempest.api.compute.servers.test_server_actions/ServerActionsTestJSON/test_resize_server_confirm_from_stopped_id
2.
3.

Actual results:
VM remains in SHUTOFF state, fails to migrate, and never resizes

Expected results:
VM resizes
