Hi Ignazio,

Please use the [octavia] tag in the subject line as this will alert
the octavia team to your message.

As the message says, this is a nova failure:

{u'message': u'Exceeded maximum number of retries. Exhausted all hosts
available for retrying build failures for instance
5abc100b-5dc8-43f5-9e1c-e6afea0242d9.', u'code': 500, u'details': u'
File "/usr/lib/python2.7/site-packages/nova/conductor/manager.py",
line 581, in build_instances\n    raise
exception.MaxRetriesExceeded(reason=msg)\n', u'created':
u'2019-01-07T15:15:59Z'}

I recommend you check the nova logs to identify the root issue in nova.

If this is related to the security group issue you mentioned on IRC,
make sure you create the security group for the Octavia controllers
under the account you are running the controllers under. This is the
account you specified in your octavia.conf file under the
"[service_auth]" section. It is likely you are creating the security
group under a different project than your controllers are configured
to use.
