Copy pasting my comment from the other bug:
"It looks like the following nova change introduced a regression in our handling of "delete while booting" instances:
https://review.opendev.org/c/openstack/nova/+/702368
and this bug has apparently already been reported:
https://bugs.launchpad.net/tripleo/+bug/1892837
We will need to fix this in nova and backport it through to ussuri."
Marking this as High because it's a regression.
