"Unable to determine ip" after server launch

[René Ras]

I may have found a bug in version 5.3.2. After launching a server it gets stuck in "Pending".

After digging in the logs  ( step 4 ) I found that that the msg_sender.py throws an exception because of an undefined IP somehow ( while the IP is known in step 1 ) 

It happens on this line:

https://github.com/Scalr/scalr/blob/master/app/python/scalrpy/msg_sender.py#L141

These are the steps taken:

1. Server is launched ( cloud specific properties )
- Status: ACTIVE
- IP: x.x.x.x ( correct IP )

2. Scalarizr on server sends HostInit message and awaits ack

2015-04-08 11:11:58,580+02:00 - DEBUG - scalarizr.messaging.p2p.producer - Message 'HostInit' delivered (message_id: 4ffe31e5-a751-482a-8cf8-64633deb49b6)

2015-04-08 11:11:58,599+02:00 - DEBUG - scalarizr.messaging.p2p.consumer - Waiting message acknowledge event: HostInit

3. On Scalr server internal messaging I do see the received message awaiting processing:

- type: in / HostInit

- status: Pending processing

4. After inspection in the logs I found the following exception:

[07/Apr/2015 10:55:35][          msg_sender][1.1][7732]    WARNING Delivery failed, message: 7344d83b-ee1c-4f25-aada-9661959c4ba2, server: {u'server_id': 'ac0360f0-1979-4642-9f86-3807057821e2', 'scalarizr.ctrl_port': 8013, u'local_ip': None, u'farm_id': 2, u'platform': 'openstack', u'farm_roleid': 6, 'scalarizr.key': '******', u'remote_ip': None}, reason: <type 'exceptions.Exception'> Make request failed, reason: <type 'exceptions.Exception'> Unable to determine ip

    file: /opt/scalr-server/embedded/scalr/app/python/scalrpy/msg_sender.py, line: 182

I've searched the Wiki and have checked all configs. As the IP is known in step 1, I don't think this issue is the result of a misconfiguration. What gives ?

Thanks
