[one-users] Using USER template variable in VM Template

[Ruben S. Montero]

Hi

If you look at the output of the XML, -x option, there is something like:

  <USER>
    <ID>6</ID>
    <GID>1</GID>
    <GNAME>users</GNAME>
    <NAME>demo</NAME>
    <PASSWORD>89e495e7941cf9e40e6980d14a16bf023ccd4c91</PASSWORD>
    <AUTH_DRIVER>core</AUTH_DRIVER>
    <ENABLED>1</ENABLED>
    <TEMPLATE/>
    <DATASTORE_QUOTA/>
    <NETWORK_QUOTA/>
    <VM_QUOTA/>
    <IMAGE_QUOTA/>
  </USER>

You can access to anything inside the <TEMPLATE/> element, empty by default.

There is no direct way to include that information in a VM Template.
This can be done at the API level with some hacking. (Unless you add
NAME to TEMPLATE)

The original set of pre-defined variables UID, TEMPLATE aren't
obviously up-to-date. I've filled an issue to address this for the
next release [1].

Thanks

Ruben
