Dynamips/Dynagen supports the interconnection of dynamips router interfaces with a real, in my case ethernet, network cards. In this case I'm focusing on linux OSs. Within the article "Connecting GNS3 with a VirtualBox host" I'm describing how to do that for GNS3 and Windows 7 environment.
Actually there are several ways how to emulate JunOS routers using GNS3 and make to usable them for advanced networking topologies. So, be able to make and run JunOS inside of GNS3 we could use:
This article explain how to make and install JunOS router using junos olive package (.tgz) installed inside of a Qemu virtual machine with FreeBSD running inside, all under Win 7 64bit OS environments. Junos olive package is an original domestic Junos package modified running inside of Olive environment (inside of PC, not router HW).
This article explain how to install a Qemu based FreeBSD virtual machine under Win 7 64bit OS. The reason for making this tutorial is the usability of Qemu FreeBSD machine inside of the GNS3 network simulator, where the FreeBSD is used as the framework for running JunOS Olive routers.
This article explain how to make a JunOS router running inside of a qemu virtual machine in the win 7 64bit environment. The Junos qemu machine is planned to be used inside of GNS3. The tutorial is based on different sources which I have to go through, for example:

Running ASA 8.02K8 inside of the gns3 on win 7 professsional 32bit caused, that console is hanging and did not answer, stay clear.
