Public bug reported: Last time I experienced simillar issue to: https://bugs.launchpad.net/mos/+bug/1422686 https://bugs.launchpad.net/nova/+bug/1378459 https://bugs.launchpad.net/nova/+bug/1460308 https://bugs.launchpad.net/nova/+bug/1407664
Shortly, horizon and 'openstack port show' are showing correct info about attached interface to instance, but 'openstack server show' has no info about network interface (also openstack server list has many empty entries instead of ip addresses). So after hard reboot of instance or hypervisor restart, the instance is booting without network interface. I found that problem is with missing information in instance_info_caches table, which has value "[]" in network_info field, for example: mysql> select * from instance_info_caches where instance_uuid = 'e615b76e-f61a-4703-a383-f58dbf1a4ffe'; +---------------------+------------+------------+-------+--------------+--------------------------------------+---------+ | created_at | updated_at | deleted_at | id | network_info | instance_uuid | deleted | +---------------------+------------+------------+-------+--------------+--------------------------------------+---------+ | 2017-12-27 15:20:51 | NULL | NULL | 99314 | [] | e615b76e-f61a-4703-a383-f58dbf1a4ffe | 0 | +---------------------+------------+------------+-------+--------------+--------------------------------------+---------+ I tried to delete the row from the table, but nova recreates the entry in the same way. So the only solution is delete neutron port and attach new interface to instance. The issue affects instances when single or multiple are created at once, so I think it's not related to bug #1422686.
