Open Stack

Hi,

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).

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 ?

Alex
