Mani,
I'm sorry for the delay in getting back to you. I would suggest using the
cluster (or subimage) functionality to do this. If I were to set this up with
linux, here is what I'd do:
-create a parent image (this would be for the top node in your pic)
-create a child image (this would be for the bottom node in your pic)
-create a script on the parent that does everything needed to configure the
parent for having the additional private network - note that a config file for
the cluster gets placed in /etc/cluster_info that contains the parent and
child IPs
-create a script on the child that does everything needed to configure the
child for having the additional private network (again, use info from
cluster_info if needed)
-create /etc/init.d/vcl_post_reserve on the parent and on the child that will
kick off the network config scripts
One thing to note when using vcl_post_reserve is that it runs after the user
clicks the Connect button. That means if the script take a little while to
run, the image won't fully be ready until after the scripts have run, but
there is currently no notification to the user as to when the scripts finish.
To set this up, you'd need to make 2 imaging reservations, one for the parent
and one for the child. Then, you'd do the above steps, and save the images.
Finally, you'd edit the image profile for the parent, expand the advanced
options, and add the child as a subimage.
I didn't test this, but I think I listed all of the steps that would be
needed. Let us know if you try it and how it works out.

Josh,
I want to make private network among virtual machines in VCL. As far as I
understood, we can have just two network interfaces on each images. But I
need to have more interfaces on each virtual machine and also these virtual
machines have their own network configuration. For example if I have two
virtual machine, I want to make a red link like what has been shown in
following picture:
http://i44.tinypic.com/14tjl4.jpg
At last, I wanted to make some images for each user. when user comes to the
system, he/she will choose those images and then system must load these
images with network configuration among them.
What option do I have to make such a configuration?
Best Regards
Mani

Mani,
Can you explain what you mean by network restrictions? VCL doesn't
actually
do much with network configuration yet, though that is quickly becoming
a
higher priority.
Under Manage Groups, you can set how many concurrent reservations a user
group
is allowed to have. Any users in that group will be able to make the
number
of concurrent reservations specified for that group. For users in
multiple groups, the maximum value for concurrent reservations of all
their groups is
used.

How can you do that?
By the way, it is not a problem here, the problem is the network
restrictions among these VMs.

Hello everyone,
I just have a question here about using XML RPC for making a
network of Virtual Machines. As far as I understood, each user
can make one reservation at the same time, so I need to make
some fake users for
each
real user and then this user can use those resources at the same
time. But the problem here is that I can't make network
restriction trough the RPC calls. what is the easiest way to
set up network restrictions in VCL?
Best Regards
Mani
