I am new to the current environment. I just asked around, and you are
correct: we had to use a mix of both buster-train-backports and
buster, because some of the packages were breaking systems scripts,
also there was one python-nova that caused the rabbitmq to get into an
endless loop...

Is it possible to just upgrade this package to some later package from
Train, which does not have this bug, in order to work around this
particular buggy state? we could do some tests here, we do have a test
system, which is built the same way, and it is suffering from the
exact same live migration issue ..
