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
|
|
# Interface on which you would like to access services
|
|
HOST_IP_IFACE=ethX
|
|
# 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"
|
