Hi Nova Team,
With the latest cloned Pike repo (devstack based setup), nova instance launches always fail with the following error:
>From Nova Conductor Logs
[u'Traceback (most recent call last):\n', u' File "/opt/stack/nova/nova/compute/manager.py", line 1855, in _do_build_and_run_instance\n filter_properties)\n', u' File "/opt/stack/nova/nova/compute/manager.py", line 2094, in _build_and_run_instance\n instance_uuid=instance.uuid, reason=six.text_type(e))\n', u"RescheduledException: Build of instance ebff9064-f7c2-402a-8ae9-95d78aee8c24 was re-scheduled: operation failed: domain 'instance-00000001' already exists with uuid 98bc86be-104d-416f-b608-ed4dbb99a674\n"]
In the 'nova show <vm> ' output says like:
File \"/usr/local/lib/python2.7/dist-packages/oslo_db/sqlalchemy/enginefacade.py\", line 398, in _create_session |
| | self._start() |
| | File \"/usr/local/lib/python2.7/dist-packages/oslo_db/sqlalchemy/enginefacade.py\", line 484, in _start |
| | engine_args, maker_args) |
| | File \"/usr/local/lib/python2.7/dist-packages/oslo_db/sqlalchemy/enginefacade.py\", line 506, in _setup_for_connection |
| | \"No sql_connection parameter is established\")
However, nova-manage --debug api_db sync works correctly.
We have not configured CELLSV2 inside local.conf and so are using the default configurations.
We see a bug filed under Nova here: https://bugs.launchpad.net/devstack/+bug/1734510
but the bug has been in 'Undecided' for a while now.
Is there a workaround for this problem?
