</div>
<div>sorry still not quite what I'm after ... so, when I use the Horizon Dashboard (or the nova api client) I can create a VM that will then get a name allocated based on what I named it, or, what I chose as a prefix if I want to provision 2 or more instances
(uuidgen is used i guess).</div>
<div><br clear="none">
</div>
<div>as I will have the same domain + the same IP ranges set for all projects, there will eventually be 2 hosts would get the exact same name, if I were to put something in place that'll automatically update my DNS - how can I change nova/horizon to add a ".$project_name"
to a VM's name, or do I simply change the OS's hostname config and the nova-api & horizon dashboard will pick that up ? </div>

You can also pass user-data on Horizon, it's one of the window tabs in the launch instance dialog.
