What I have found is if I invoke the nova-manage program from within the
Bourne shell while logged in as root

sh-4.1# python /usr/bin/nova-manage db sync nova

which is what I think the intent of the command su -s /bin -c "nova-manage
db sync" nova  is trying to do.

File "/usr/lib/python2.6/site-packages/nova/db/sqlalchemy/migration.py",
line 39, in db_sync
    raise exception.NovaException(_("version should be an integer"))

​The value of version is "nova" and of course that throws a ValueError
because "nova" is a string that can't be converted to an integer.  I am
trying to track down where it is coming from.
