This is due to https://review.opendev.org/815020 which merged a week ago to update the default CPU model in DevStack with one which will work for CentOS 9. See also this mailing list post and its replies which go into greater detail on the situation:

You can probably override LIBVIRT_CPU_MODEL in your configuration setting the old default of "none" if you want the old behavior for now, though there are likely better long-term solutions.
