Again there are two options:
 
* Build the XVA using DevStack in Dom0 (note: default [[XenServer]] 6.0 install will not leave enough free space)
 
* Build the XVA on different machine, then copy the XVA to the [[XenServer]]
 
 
 
The basic process is:
 
* [[XenServer/Install|Install XenServer]]
 
* prepare_dom0.sh - installs git in Dom0
 
* Write a DevStack config file, that matches your setup
 
* [prepare_guest.sh - optional - if it is not run, next script pulls image from web]
 
* build_xva.sh - create the DevStack VM image (in XVA format)
 
* build_domU.sh - install xapi plugins, and Open vSwitch isolation rules, and xva image
 
* On boot the XVA image runs stack.sh
 
 
 
You can read more about this in the readme:

DevStack and XenServer

DevStack is a great way to get started with OpenStack. XenServer and XCP are great ways to use the Xen hypervisor that powers some of the world's largest clouds.

To get started, you first you need to install XenServer or XCP on a physical machine.

Then there are two possible ways forward:

  • Create your own Ubuntu PV VM on your XenServer, set VIRT_DRIVER=xenserver, and then run stack.sh
  • Use the readme in tools/xen to build an Ubuntu PV VM for you

There is also a script which may help automate devstack installation on XenServer hosts (or other XenAPI-based hosts such as XCP hosts): https://raw.github.com/citrix-openstack/qa/master/install-devstack-xen.sh

Installing DevStack on your own Ubuntu paravirtualized VM

This is not really heavily tested, you are probably best using the approach above.

Please note:

  • The VM must be running in PV mode (/sys/hypervisor/uuid is needed)
  • It must be on the same hypervisor as the one you are managing

Useful Notes

Please note:

  • For nova to work correctly with a XenServer pool, it must be created using the Host Aggregates feature
  • It is intended that every XenSever has a VM running (as a minimum) the OpenStack compute worker
  • When using Host Aggregates, you still have a VM on every member of the pool
