Failure logs based around resize request

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

Comment 1 smooney 2022-05-13 15:47:30 UTC 
i dont know if this is the cause but ti looks like 

https://review.opendev.org/c/openstack/ovsdbapp/+/818446
has not been backported https://wimp.usersys.redhat.com/?change_id_input=+Ibd3c7427cbcab81253e0ed700174be09908bdef7

so we should ask the networking dfg to do that.
we can see its blocking the nova compute agent in the log output of the job

that also need python3-openvswtich  2.16+ to be installed

Comment 4 smooney 2022-05-13 16:21:09 UTC 
when looking at theh logs we noticed that the compute agent is being blocked by ovs. we ware cloning this into separate bugs to tack backporting the os-vif and ovsdbapp patches that work around the os issue.
we can keep this to investigate the ci issue incase its unrelated to the ovs issue.
Comment 5 smooney 2022-05-25 14:09:47 UTC 
looking at the latest build for the affected jobs while they are still failing on other test the one in question appear to now be working
as such i think we should close this specific bz as i don't think there is anything actionable.

the other bz for the ovsdbapp backport and os-vif backport are till valid enhancements so can remain open seperately
