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.
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
- 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
