failed to launch an instance from ISO image: TRACE nova.compute.manager MessagingTimeout: Timed out waiting for a reply to message ID

[Yogev Rabl]

Description of problem:
The Openstack is installed as AIO (with nova networking) on fedora 20. The instance was launched on a flavor that has the following parameters:
+--------------------------------------+-----------+-----------+------+-----------+------+-------+-------------+-----------+
| ID | Name | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor | Is_Public |
+--------------------------------------+-----------+-----------+------+-----------+------+-------+-------------+-----------+

| 8ddee6ea-c7b3-4482-97b3-f4c9ca6a2c19 | m1.medium | 4096 | 40 | 40 | | 2 | 1.0 | True |
+--------------------------------------+-----------+-----------+------+-----------+------+-------+-------------+-----------+

On the first try the instance status was stuck on 'spawning', even after a time out stopped the process.
On the second try the instance status was changed from 'spawning' to 'Error'.

How reproducible:
100%

Steps to Reproduce:
1. upload an ISO image.
2. change a flavor to have the same parameters as it shows above.
3. launch an instance.

Actual results:
The launch fails.

Expected results:
The instance is up and running.

This is a generic error (MessagingTimeout). Is your openstack deployment otherwise working? Are you able to launch instances successfully from other types of images and/or flavors?
