18 Virtual Machines Linux Debian Wheezy. Their only difference is their name.
The installed software are similar to the ones of NetKit.
VM are integrated into GNS3 and VirtualBox
Be careful : several services (isc-dhcp-server, bind9, samba, ...) are downloaded but not installed. You must install them for use them (aptitude install/apt-get install), but you don't need access to Internet for that.
Should it be needed, additional software can also be installed (as with a real Debian Linux) in order to enable particular features that are required for specific experiments.

A basic configuration file for the Cisco routers (/opt/raizo/user/GNS3/Cisco/Config/baseconfig_cisco.txt)
For nano, a syntax highlighting for the configuration files
For tmux (installed only on VM), the key "CTRL+ARROW" allow to change terminals fastly.
Colorized outputs of networks commands
minicom of Raizo is configured to get connected to the serial port. minicomUSB (or minicom USB Ÿ) allows to use an adapter USB.

fast-ip : configuration of IP address and eventually the gateway.
fast-dhcp : configuration of a DHCP server based on the IP address of the server
fast-dns : DNS server configuration
fast-rip : RIPv2 router configuration
fast-syslog : displays in color the last 40 lines of the file /var/log/syslog
(fast-ip, fast-dhcp and fast-dns used together enable to setup a dynamic DNS)

fast-backup-lab : backup of the GNS3 project with VM.
fast-restore-lab : restore a GNS3 project, which has been saved.
fast-reset-vbox : reset all the Virtual Machines
fast-clean-crash-gns3 : kill all the processes used by GNS3 (in case of a crash for instance)
fast-mountUSB : mount the USB key in the directory /media/usb0
fast-startup : mount automatically the USB key in /media/usb0 and processes the script /media/usb0/raizo.startup
fast-update: download the file http://UpdateRaizo/raizo.sh (or the file in parameter instead of raizo.sh) and processes it.
fast-memo: display a reminder in French.
fast-battery: display the percentage of energy remaining in the battery.

After having started up, the hostname of each VM will automatically take the name that was given in GNS3
After having started up, the VM execute the script on Raizo "/home/user/VMStartup/VMRaizo.startup" then "/home/user/VMStartup/X" with X the hostname of the VM
As with NetKit, the VM have access to the directory “/home/user” of Raizo by using their directory /hosthome

Persistence of /home : When booted, if Raizo finds a partition with the label “persistence” and the file persistence.conf with "/home" on the root, this partition is automatically mounted in /home.
Be careful : Don't forget to erase your persistent user's home if you update "Live Raizo"

For to save the configuration of VirtualBox and GNS3, you can save with fast-backup-lab/fast-restore-lab an empty projet of GNS3
Think to glance into the default history of commands from Raizo and VMs
BIOS time must be updated otherwise the VMs won't start
