[one-users] Add network context variables automatically

[Oriol Martí]

Hello,
after looking the mechanism of the contextualization variables to set 
the network configuration, my idea is to pass the network parameters 
with contextualization, my idea is to add to the context variables the 
IP, netmask, DNS,... of the related NICs.

I've been thinking to add a hook on create a VM, but I don't know if I 
can modify the context variables at this point, does anybody know if is 
possible?
Maybe another solution could be launching the hook on the physical node 
and modifying directly the cdrom image that opennebula creates, but I'm 
not sure if this procedure it will be good because maybe the cdrom image 
is not created when the hook is launched and can fail easily.

Does anybody know if is possible to do? Maybe the only solution is 
modifying source code? Where can I start?

Thank you all,
