Vagrantfile

#############################################################################
# This VagrantFile defines two configurations:
#
# Config 1:
# A separate VM for API server, git server, a server for support services
# such as MySQL and RabbitMQ, and DevStack that has Nova with Docker driver
#
# Config 2:
# One VM for DevStack with 'Dockerized' Nova and one VM for the rest of
# the components
#
# Set ENV['DEVSTACK_BRANCH'] to change the devstack branch to use
# Set ENV['SOLUM']='~/dev/solum' path on local system to solum repo
# Set ENV['SOLUM_CLI']='~/dev/python-solumclient' path on local system to solum repo
# Set ENV['SOLUM_IMAGE_FORMAT'] to "vm" if you don't want docker
