Public bug reported:
In a stable/queens devstack environment with multiple PowerVM compute
nodes, everytime I see this in [email protected] logs:

The nova_cell1.conf does have [database]connection set:

connection = mysql+pymysql://root:[email protected]/nova_cell1?charset=utf8
This may be related to https://bugs.launchpad.net/nova/+bug/1736946 ,
though that is supposedly fixed in stable/queens and the trace is
different, hence the new defect.
