Comment 165 for bug 1996188

I am trying to reproduce the bug with a focal/ussuri openstack and step 4 (creating the VM) is failing for me with error:

2023-01-30 11:45:24.823 62889 ERROR nova.compute.manager [req-54de4256-c3b0-46d9-9fa3-e1b17a81e5cb 7e70ed49536144699c3b2202b699b2a9 39b49452b4184ba4a07df3f50e600de8 - 1a40c665d79e45e6ba

My nova version is:

Can you please tell me on which nova version are you seeing this issue?
