So, in general I don’t think this will fly because it’s my understanding the
OpenStack servers only test fully open source code. Allowing a third party
vendor system to run on the OpenStack servers as part of any functional
testing would open an entirely new can of worms here. I would suggest
asking this question on #openstack-infra as well for clarity since I don’t see
a response on the mailing list yet.

Thanks,
