So devstack is explicitly not intended to be used to actually install and
*use* Openstack. It's intended for development and Continuous Integration
testing. From the devstack FAQ:
"Can I use DevStack for production?

DevStack is targeted at developers and CI systems to use the raw upstream
code. It makes many choices that are not appropriate for production

In spite of that, a disturbing number of real world Openstack installations
have been done via devstack. The usual result of that is tears from the
operator some months down the track.

Openstack Ansible is arguably a better choice, but it depends on what the
installation environment is (a single host, several hosts, bare metal or
VMs) and what you intend to do with it.


By the way, whatever method you choose to use, don't just do it straight
onto a computer that you care about. Either use a VM, a cloud instance or a
machine sacrificed completely to Openstack. The installation will do things
to network and other configs that really won't make you happy if the
machine is to be used for anything else.
