Believe me... the most cool open source "interface for Xen" is Eucalyptus...

    First, thanks all of you for your encouragements.

    To Grant McWilliams :
    So far, I just use RPC to control Xen daemon : the API is well
    documented. See

    My soft can run on every machine with a web server + PHP5 and sqlite.
    Just need a connectivity with the Xen daemon. Yes, it can works
    accross Internet or every networks (but be sure to use encryption !)

    So, no root or other stuff like that. In my case, I choose to make
    things simple : just an htaccess (so far).

    With the API, you've got access to the entire Xen daemon, but I think
    it's not so hard to restrict an user to a VM (or more). It's "just" an
    added layer, can be interfaced with ldap, mysql or pgsql database,
    with adaquates informations on users.

    Just an example of Xen architecture + XenOrchestra :

    Dom01               Dom02           Dom03
    ___|_____________|____________|__________ (network)
                |                     |                     |
         Xen orchestra      client           other client

    As you can see, clients are contacting the Xen Orchstra web interface,
    and then, this one check Dom0's with Remote procedure call.

    With this, you can do everything you want. Just need to implement it !
    Limitations are the API, which suffer from certain shortcomings (like
    impossible to differenciate a migrated or an halted VM).

    For your "feature request", I think I'll do, but in a first time, my
    goal is to admin Xen easily. But ASAP, I'll try to respond to your
    And as it's a open source project, everyone can contribute, so.. more
    we are, more the project will be great :)



    P.S : sorry if there is misspelling in my text, I'm not perfect in
    English ;)

Do you have some screen shots to show us how Eucalyptus works?
