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 a few possible ways forward:
- Using the script at https://raw.github.com/citrix-openstack/qa/master/install-devstack-xen.sh - running this from off-box on a fresh install of XenServer will push down ssh keys and install devstack using the default settings.
- Use the readme in tools/xen to build an Ubuntu PV VM for you
- Create your own Ubuntu PV VM on your XenServer, set VIRT_DRIVER=xenserver, and then run stack.sh. You will need to set up networking manually to meet your specific needs
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
