Public bug reported:
Operating steps:
1. nova boot a instance named 'A' on host named 'hostxx'.
2. use 'systemctl stop openstack-nova-compute' command to stop nova-compute
service on hostxx.
3. use 'nova delete' command delete instance A, and the result is successful.
4. Then use 'systemctl start openstack-nova-compute' command to start
nova-compute service on hostxx.
5. wait 30 minutes, the periodic tack named
'_cleanup_running_deleted_instances' will execute to delete the instance A on
hostxx and the exception InstanceInfoCacheNotFound occurs. (You can modify the
value of 'running_deleted_instance_poll_interval' in file /etc/nova/nova.conf
to reduce the waiting time)
the nova-compute.log on hostxx:
