Bug 1048334

+++ This bug was initially created as a clone of Bug #1048319 +++

Description of problem:

heat-* services fail to start on RHEL 6.5

Version-Release number of selected component (if applicable):
Version     : 2014.1
Release     : 0.1.b1.el6

How reproducible:

every time with a fresh install on RHEL 6.5 through packstack

Steps to Reproduce:
1. fresh install 
2. service openstack-heat-api start
3. see logs

Actual results:

does not start

Expected results:

heat should start

Additional info:

at first, heat cannot start due to a database problem.

tried a workaround dropping the db and reinitializing but this is the result

[root@rhel6 heat]# openstack-db --service heat --drop

Dropping 'heat' database.
Complete!
[root@rhel6 heat]# openstack-db --service heat --init

Creating 'heat' database.
Initializing the heat database, please wait...
ERROR: No module named sqlalchemy
ERROR 1146 (42S02) at line 1: Table 'heat.migrate_version' doesn't exist
Final sanity check failed.
Please file a bug report on bugzilla.redhat.com against the openstack-heat package.

at this stage, there are 3 candidates for python-sqlalchemy:

- version 0.7 from epel6 that is actually installed
- version 0.5 from rpm-updates. If installed conflicts with 0.7.
- version 0.8 from epel6 that cannot be installed due to priority problems.

So this is an issue with low level heat-manage command needed in this work around situation. I'm guessing that heat-manage has not been updated to select the parallel installed version of sqlalchemy and that nova-manage has.
