Warning

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. Use this to get started quickly. It is far from the only way to setup OpenStack using Xen.

Required Hardware

To get started, this is probably what you want:

  • Cheap switch (most home routers will do)
  • Linux machine
  • 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 one network cards
  • assuming you have your home switch/hub/router is setup as a VLAN trunk port.
  • use nic0 (the bridge called xenbr0) to have the management network

Steps to get OpenStack running on XenServer

Here is what you need to do:

Steps to add a second compute node

Once you have your first machine working, it is possible to add a second XenServer host to your cloud using a very similar procedure.

You need to select what service you want to run on the second node, 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 (assuming you chose MULTI_HOST=true on the first node):


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