Figured I'd try packstack-ing a Liberty on centos7.1
How did you install centos 7.1?
Packstack failed to install Cinder due to missing: python-cheetah
After manually installing Python-cheetah, Cinder installed.
Also missing python-werkzeug for Ceilometer.
To be clear, both deps are correctly expressed as Requires: in cinder
and ceilometer .specs.
Those two packages are in extras repo which is enabled out of the box
in the default centos install.
I guess kickstart you're using disables it?
Cheers,
Alan
