This is still a work in progress.

Getting started with XenServer and OpenStack

This is an opinionated guide to setting up an OpenStack Cloud using Xen/XenServer/XCP. Use this to get started quickly. It is far from the only way to setup OpenStack using Xen.

Installation Video

You can find a video for the installation using Devstack here.

Required Hardware

To get started, this is probably what you want:

• Cheap switch (most home routers will do)
• Linux machine (preferably, running Ubuntu 11.10)
• XenServer capable machine
• (optional) Windows machine to run Citrix XenCenter (the official XenServer GUI)

Planning your Deployment

The most important part of planning is getting your head around the networking.

Take a look at the diagram in the wiki page on XenServer deployment.

It is probably best to configure your XenServer like this:

• assuming two network cards
• use nic0 (the bridge called xenbr0) to have management networks

(TODO: provide example xenrc file for devstack)

Steps to get OpenStack running on XenServer

Here is what you need to do:

• Install XenServer 6.0.2 by running the CD install
• Follow the post install steps
• Use DevStack to create the XVA image for the VM that will run the nova services
• Prepare XenServer with xapi plugins and vif isolation rules
• Install the VM

Steps to add a second compute node

You can use DevStack to deploy a node that only has nova-compute and nova-network, and modify the configuration so that it talks to your other node's MySQL, Rabbit, Glance, Keystone, etc. You probably want to add something like the following in your localrc file:

MASTER_SERVER=111.111.111.111 #replace with ip of your first server
ENABLED_SERVICES=n-cpu,n-net
MYSQL_HOST=$MASTER_SERVER
RABBIT_HOST=$MASTER_SERVER
KEYSTONE_AUTH_HOST=$MASTER_SERVER
GLANCE_HOSTPORT=$MASTER_SERVER:9292
