Installing JunOS Olive12.1 in VirtualBox on Linux

If you don't have a real Juniper equipment, there is way to practice with  JUNOS. Of course best way is to have the actual Juniper router since many functions cannot be simulated/emulated. Googling around you will find different methods either using VirtualBox, VMware or Qemu. Methods vary from extremely easy to difficult ( if you want to do it from scratch using FreeBSD - JUNOS is based on FreeBSD kernel.)
Below you can find instructions in 5 steps on how to install JUNOS Olive 12.1 in VirtualBox on Linux. For more details and capabilities of JUNOS Olive check this excellent website.
