Most people who use the Mininet network simulator will download and set up the Mininet virtual machine image. However, there are times when we may want to use a different version of Mininet than the one already installed in the Mininet VM.

For example, we may want to use the newest features of Mininet currently being developed. The Mininet project releases beta-quality source code that user can download and install themselves.

" q9 @6 C; p% S$ P5 I( u) gThe Mininet install script may overwrite files in your home directory (depending on what you already have installed)1. If Mininet makes changes that cause problems on an existing virtual machine, you can just delete the VM and try again with a fresh Ubuntu Server image. But, if you install Mininet directly on your host computer you may cause problems.
