With python version 3.7 and any nova version before Stein, live migration results in a deadlock.

I'm asking this question so I can answer it -- the fix is in place in Stein but a bug was never opened against Nova so it's pretty hard to diagnose.

Rocky basically doesn't work on python3.7 (the version shipped on Debian Buster) because of issues with threading.

This is fixed in version Stein with the following patch: https://review.opendev.org/#/c/624740/

There is no non-code workaround as far as I know.
