How To - Step By Step Installation of JunOS on GNS3 [Part 4]
Testing
To check if everything work, let’s configure 2 Olives:
root@%cli
root>edit
[edit]
root#
[edit]
root#set system root-authentication plain-text-password
New password:
Retype new password:
[edit]
root#set interfaces em0 unit 0 family inet address 10.0.0.1/8
[edit]
root#commit
commit completeConfigure the other device using the same commands but with another IP address (e.g. 10.0.0.2/8) and ping.

Updating JunOS
You can update your version of JunOS from the CLI with the following command:
request system software add [jinstall_package]
Running your router(s)
Now you have a base olive image. Qemu allows you to use this as a base for other images and only writing the changes to your “slave” images saving on disk space! You can also use less memory for each Qemu instance.
Create a new image off of your base image. Repeat for all your routers you want to emulate:
qemu-img create -b olive-base.img -f qcow2 R1.img
Start your router and then telnet to it:

This article explain you how to emulate Juniper JunOS on a PC using Qemu. This is an updated and enhanced version of excellent howtos from Juniper Clue and Internetwork Pro as well asHimawan Nugroho’s blog. I mainly focused on Qemu, so if you wish to install JunOS on a real PC or using VMware, please have a look at the Juniper Clue article for more information (and of course Google).
So what’s new you would say? First, I chose to use the latest version of Qemu: the 0.11.0 which supports the Intel e1000 network card emulation since version 0.10.0. and includes several fixes for it. I have modified and adapted the old patch for Qemu 0.11.0, it includes the UDP tunnel (connection to Dynamips/GNS3), PCAP and LCAP support. Also, the patch allows multicast traffic with the e1000, i82557b and i82559er Qemu emulated network cards. Moreover, this article show how to emulate JunOS on multiple operating systems: Mac OS X, Windows XP and Linux Ubuntu 9.04 without using an untrustworthy obscure binary downloaded from a forum you can’t even read the language

How To - Multiple Olives On One Box Using Vmware
Creating virtual serial ports for telnet access (so no physical com port access required)...
Having one Olive box is great for CLI familiarity but multiple Olives interacting with each other is the only way to really get to grips with the routing protocols and route filtering techniques. Once one Olive session is fully built, it's a piece of cake to mirror this so you can have 2 or 3 or more (resources dependant) on one box. The main limiting factor of this approach is the lack of physical serial ports on the server. Mine only has a single COM1. To get round this, I used the FREEWARE HW Virtual Serial Port v2.5.10 software from HW-group. Using the command line (or creating shortcuts in the Windows user profile startup folder so it was persistent), I created 3 new virtual serial ports that were setup as telnet servers (COM2 on port 2009, COM3 on port 2010, COM4 on port 2011) so I can telnet to these and be "attached" to the various Olive console ports. Yes, this does mean my doctoring of the cable above was interesting, but not entirely necessary.
