The standard Nodepool population looks like:

Whereas, we need some additional entry points:

Launch server
✪ Install server - This phase will install XenServer on the server
✪ Poll install status - As installing XenServer includes rebooting the server, the best way to figure out when the installation is finished, is to try to connect to the server through ssh, and check if a specific status file exists.
Bootstrap instance
✪ Pre-snapshot script and timeout - Before taking a snapshot, we need to halt the server. Therefore we execute a halt in dom0, and ask nodepool to wait for a specified timeout. The timeout should be enough for the server to halt.
Snapshot server
Populate pool from snapshot
✪ Poll status file on node launch - As starting the image invlolves an automatic reboot, we again need a proper way to make sure, that XenServer is up and running. This could be achieved with the same polling mechanism that we used for Poll install status.
Node is ready when it's accessible through SSH

⌛ - WAITING - https://review.openstack.org/68181 - Add XenAPI package to requirements - this way, it will be cached by Openstack's PyPi mirror.

✔ - MERGED - https://review.openstack.org/68136 - modify devstack, so gate will pre-cache the image (cirros vhd tgz)
✘ - MISSING - Move dom0 modifications to stack.sh
- The incubator for the modifications is here: https://github.com/citrix-openstack/xenapi-os-testing/blob/master/launch-node.sh Search for the string:
```
SSH_DOM0
```
  to find dom zero modifications.

✘ - OUTDATED - https://review.openstack.org/60581 - Script to convert an image to a XenServer
- The incubator for this script is here: https://github.com/citrix-openstack/xenapi-in-the-cloud
- The incubator needs to be tagged, and released, the changeset should be updated
✘ - OUTDATED - https://review.openstack.org/60902 - Add node type of devstack-xenserver
✘ - OUTDATED - https://review.openstack.org/60903 - Add in a new job to run tests on XenServer

⌛ - WAITING - Install phase - execute a script, that converts the node to a XenServer, and use polling to find out when it's finished: https://review.openstack.org/61463
✘ - MISSING - Pre-snapshot script and timeout - The script will halt the node, and the wait will make sure, that the machine has enough time to halt. It's safe to snapshot a halted server.
⌛ - WAITING - Support status file polling on node launch: https://review.openstack.org/65261

✘ - OUTDATED - https://review.openstack.org/60900 - Support XenAPI driver in gate: localrc generation. - The incubator for these changes is here: https://github.com/matelakat/devstack-gate/tree/xenserver-integration
