Hi Team,
Any help in this is highly appreciated.
A new Ubuntu 16.04 box with devstack pulled off pike and stacked up
ends up with Nova boots failing.
Is this seen by others too off stable/pike?

Subject: [Openstack][Nova] Nova Instance Launches failing on stable/pike
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,

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

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?
