OpenStack via DevStack

This page is describing how to quickly deploy an OpenStack by using the development tool DevStack on a single machine. Xen via libvirt is going to be used.

This how-to describes the steps took on an Ubuntu 14.04 LTS. Little changes should be requires to do the same on the other distribution supported by devstack.

How to

We are going to install Xen then setup devstack.

• Install Xen

 sudo apt-get install xen-hypervisor-4.4-amd64
 sudo reboot

• Get devstack

 git clone https://git.openstack.org/openstack-dev/devstack

• Configure devstack

Edit local.conf in the devstack working repository. (For more options, take a look at DevStack Configuration.)

 # Needs a few more patches for Xen
 NOVA_BRANCH="refs/changes/22/146622/3"
 
 # This is a Xen host
 LIBVIRT_TYPE=xen

• Run devstack

This might take a while.

 ./stack.sh

• Done!
