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

[Hyun Woo Kim]

Hi,

Thanks very much for the response.

Actually, your answer seems a bit different from what the manual says
and what I observe.

I observe that the "USERS" actually have "TEMPLATE" attribute
which returns the contents of "user_pool" in the database
(We are using MySQL).
The contents of MySQL "user_pool" contain NAME field.
I thought these fields in DB and <user_attribute>s of USER template
somehow are related..

Let me simplify my original question.
Is there anyway to fetch the NAME field of the DB for the 
user who does "onetemplate instantiate"..?

Thanks,
Hyunwoo



Current version of OpenNebula can only access template variables from
users, or networks. By default users have an empty template, so there
is no NAME variable unless you define it, e.g. oneuser update. About
$UID, this variable is predefined so the OpenNebula core it is not
actually accessing the user information but that stored in the VM.

Cheers

Ruben
