Hello Michael, thanks for your suggestion. I solved my issue. There was some wrong configuration in octavia.conf file. Security group must belong to the octavia project. Regards Ignazio Il giorno Mar 8 Gen 2019 18:06 Michael Johnson <johnsomor@gmail.com> ha scritto:

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.
