Thanks for your answer. I was checking the bug and seems the solution is not included for ocata. I was checking my code also, and the it doesn't have the change included. Do you know if it will be backported to Ocata soon?

Hi all,

We have openstack ocata and nova version 15.1.5. There is a compute where nova-compute is down and when we try to restart it fails. In nova logs we can see the following errors:

020-03-19 13:25:15.246 9809 INFO nova.compute.manager [req-3d894696-e1b8-4b9a-908f-93ffa4b55226 - - - - -] [instance: 308eebe4-178c-486b-8a06-5a558f07aea9] Deleting instance as it has been evacuated from this host
