Getting Started With XenServer 5.6 and Devstack

The purpose of the code in this directory it to help developers bootstrap a XenServer 5.6 + Openstack development environment. This file gives some pointers on how to get started.

Install Xenserver

Install XenServer 5.6 on a clean box. Here are some sample Xenserver network settings for when you are just getting started (I used settings like this using a lappy + cheap wifi router):

XenServer Host IP: 192.168.1.10
XenServer Netmask: 255.255.255.0
XenServer Gateway: 192.168.1.1
XenServer DNS: 192.168.1.1

Prepare DOM0

At this point, your server is missing some critical software that you will need to run devstack (like git). Do this to install required software:

./prepare_dom0.sh

This script will also clone devstack in /root/devstack

Configure your localrc

Devstack uses a localrc for user-specific configuration. Note that while the first 4 passwords are arbitrary, the XENAPI_PASSWORD must be your dom0 root password. And of course, use a real password if this machine is exposed.

cd /root/devstack

cat > /root/devstack/localrc <<EOF
MYSQL_PASSWORD=my_super_secret
SERVICE_TOKEN=my_super_secret
ADMIN_PASSWORD=my_super_secret
RABBIT_PASSWORD=my_super_secret
# IMPORTANT: The following must be set to your dom0 root password!
XENAPI_PASSWORD=my_super_secret
EOF

Run ./build_domU.sh

This script does a lot of stuff, it is probably best to read it in its entirety. But in a nutshell, it performs the following:

Configures bridges and vlans for public, private, and management nets
Creates and installs a OpenStack all-in-one domU in an HA-FlatDHCP configuration ** A script to create a multi-domU (ie. head node separated from compute) configuration is coming soon!
