JUJU BOOTSTRAP TO OPENSTACK FAILS

Tue Nov 28 00:46:09 UTC 2017

Navin,

The error thrown by juju is received from OpenStack when we tried to boot
an instance.  OpenStack is requiring the name or uuid of the network to use
because it doesn't know which network to choose.  The fix for that error is
using --config network=<network> during bootstrap.

Were there any hints in the nova log regarding details for the No Valid
Hosts failure?  When you manually booted the OpenStack instance, did you
need to specify `--nic net-id=net-uuid` or `--nic net-name=network-name`?

Unfortunately I'm not familiar with Opencontrail SDN.
