Hello,
You can have a plug-and-play virtual network based on openwrt at clownix@clownix.net.
Olsr and ospf demonstration can be graphically launched and take less than 1 minute to
give an operational 6 machines network.

First of all, you have posted on the wrong forum. This forum clearly indicates for Howtos and Documentation. Secondly, all your posts are spams!

A spam is for money, you may notice that there are no advertisement at all at the mentioned site.
Then for the how-to, the download from the mentioned site is packed with them:
How-to make a KVM virtual openwrt machine from scratch
How-to make KVM debian, Fedora, Ubuntu machines from scratch
How-to make UML virtual machines OpenWrt, Fedora, Ubuntu, Debian from scratch
How-to have your virtual network inside your machine with ospf running, (or olsr).
You may not be interested, but others may be, the spam insult is not adequate.
OpenWrt is the default machine in the cloonix virtual net, I simply supposed that I could mention it here, I do not know where I should mention the existence of this new network tool.   
Documentation is not only paperwork, it can be a pointer to something that contains information. (including source code).

AFAIC, a SPAM post is a self-promo post as your posts just did.

I code a lot, what do I do to make it public?
If you have a solution for open-source diffusion without self-promo at least the first year after a product is born, tell me, I am receptive to any suggestions.
You are not into virtualization and networks, but I am into those themes, I use my portable network every-day to code network-related stuff, I use my debian virtual machine but OpenWrt is so light that I have elected it to be the official default machine.
My site is the HOW-TO have a 40 OpenWrt virtual network with a graphical interface. Double-click on a machine to have an ssh terminal on that machine, create and destroy lans with mouse clicks...
A little self-promo to launch the code does not hurt anyone and the software seem to make people happy when they try it.

I don't know about you and/or anyone. However, if I had to do what you wanted to do, I would contact the site admins/moderators to let them know and/or ask them to provide link to your site. So far, I don't see no site admins nor moderators on this forum enforce the spam rules.

Thanks, at least you did react to my "spam" and suggested something. I would like to contact moderators, but this is never easy on any forum, and I feel it is even more impolite than to post here. If this is not appropriate, well they will just erase the thread, I will not "spam" here anymore, I have seen that most of the OpenWrt forum is more hardware-oriented. I discovered OpenWrt only recently because different users of cloonix-net wanted me to add this target to my virtual network to play with simulated wireless networks. I found the creation of OpenWrt from scratch very pleasant and its small size made it an ideal demonstration target for my network.  You probably use OpenWrt on real hardware, but OpenWrt, having only small needs in resources, can be used for large-scale wireless network emulation and this new way of using OpenWrt should only bring more fame to it.
