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 (or greater) + Openstack development environment. This file gives some pointers on how to get started.
Xenserver is a Type 1 hypervisor, so it needs to be installed on bare metal. The Openstack services are configured to run within a "privileged" virtual machine on the Xenserver host (called OS domU). The VM uses the XAPI toolstack to communicate with the host.
Step 1: Install Xenserver
Install XenServer 5.6+ on a clean box. You can get XenServer by signing up for an account on citrix.com, and then visiting: https://www.citrix.com/English/ss/downloads/details.asp?downloadId=2311504&productId=683148
For details on installation, see: http://wiki.openstack.org/XenServer/Install
Here are some sample Xenserver network settings for when you are just getting started (Settings like this have been used with a laptop + 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
Step 2: Download devstack
On your XenServer host, run the following commands as root:
wget --no-check-certificate https://github.com/openstack-dev/devstack/zipball/master
unzip -o master -d ./devstack
cd devstack/*/
Step 3: Configure your localrc inside the devstack directory
Devstack uses a localrc for user-specific configuration. Note that the XENAPI_PASSWORD must be your dom0 root password. Of course, use real passwords if this machine is exposed.
cat > ./localrc <<EOF
MYSQL_PASSWORD=my_super_secret
SERVICE_TOKEN=my_super_secret
ADMIN_PASSWORD=my_super_secret
SERVICE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=my_super_secret
# This is the password for your guest (for both stack and root users)
GUEST_PASSWORD=my_super_secret
# IMPORTANT: The following must be set to your dom0 root password!
XENAPI_PASSWORD=my_super_secret
# Do not download the usual images yet!
IMAGE_URLS=""
# Explicitly set virt driver here
VIRT_DRIVER=xenserver
# Explicitly set multi-host
MULTI_HOST=1
# Give extra time for boot
ACTIVE_TIMEOUT=45
# Host Interface, i.e. the interface on the nova vm you want to expose the
# services on. Usually eth2 (management network) or eth3 (public network) and
# not eth0 (private network with XenServer host) or eth1 (VM traffic network)
# This is also used as the interface for the Ubuntu install
# The default is eth3.
# HOST_IP_IFACE=eth3
# First time Ubuntu network install params
NETINSTALLIP="dhcp"
NAMESERVERS=""
NETMASK=""
GATEWAY=""
EOF
Step 4: Run ./install_os_domU.sh from the tools/xen directory
cd tools/xen ./install_os_domU.sh
Once this script finishes executing, log into the VM (openstack domU) that it installed and tail the run.sh.log file. You will need to wait until it run.sh has finished executing.
Step 5: Do cloudy stuff!
- Play with horizon
- Play with the CLI
- Log bugs to devstack and core projects, and submit fixes!
Step 6: Run from snapshot
If you want to quicky re-run devstack from a clean state, using the same settings you used in your previous run, you can revert the DomU to the snapshot called "before_first_boot"
