Description Alex Stupnikov 2021-03-26 12:43:19 UTC 
Description of problem:

Hello.

We have a customer running pretty old RHOSP 13.0.4 deployment and facing the following problem (in my interpretation):

- customer executed overcloud deployment command, which caused nova-compute restart
- nova.compute.manager:_destroy_evacuated_instances function analyzed list of local instances and tried to delete one of them (instance is still up and running on this compute node).

I have tried to compare appropriate code in RHOSP 13.0.4 and latest RHOSP 13 nova and couldn't huge differences [1], so decided to report this bug instead of asking customer to follow minor upgrade steps.

I will provide a summary about affected instance and related log messages privately.
