RHEL64-based script to build and start 3 Fedora 18 VM's for packstack.
View packstack-vms-build.bash
# This script is intended to ultimately "just work" on RHEL6, setting
# up a grizzly openstack implementation on three Fedora 18 guest VM's
# using the packstack installer. It currently does not work due to a
# dependency error with openstack-nova-conductor not being available.
# It creates 3 Fedora-18 VM's for packstack/openstack-grizzly. Each
# has two nic's. The first nic is connected to the virt default
# network. The second is connected to the virt openstackvms network

Models, Roles, Decorators, and Interactions -- A modest proposal for a toned done version of DCI that isn't as janky as Concerns.

Models, Roles, Decorators, and Interactions

A modest alternative to DCI that might be worth further thought

One of the problems with advancing the discussion on DCI is that we lack a comparable alternative pattern that has the same goals, but favors a low ceremony approach. The closest thing we have to that is Rails concerns, but they are more like distant relatives of the DCI concepts rather than first cousins, and that makes comparisions between the two approaches not especially fruitful.

I am considering the idea of experimenting with my own paradigm that captures the intent and purity of DCI, but with the convenience of concerns. Please note that this is just the starting point of a conversation, it is NOT a promise of comercially available cold fusion or a cure for cancer. It's just a gist with an idea on it I'd like to hear your thoughts on.

What if we had a top-level topology that was split into Models, **Rol

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.
