The procedures I demonstrate using GNS3 and VirtualBox on my Linux system should also be usable on computers running either Windows or Mac OS. Access to hardware virtualization support makes very noticeable improvement in performance. VirtualBox can also utilize the hardware virtualization support technologies available on most computers while Qemu can only access these features in the Linux operating system (via KVM), with restrictions. Many users of GNS3 choose to use VirtualBox to run Linux virtual machines because, like GNS3, it works the same on Windows, Mac OS, and Linux operating systems. Next, we need to install software to support running the Linux virtual machines that will be managed by GNS3.

Procedures to install GNS3 in Windows or Mac OS are available in the GNS3 documentation.

This procedure describes how to install GNS3 and its supporting software on a Linux host computer running Xubuntu 13.10.


In this post, we show how to install and set up GNS3 and VirtualBox to emulate a network consisting only of open-source routers and hosts. While there are many web sites and online tutorials dedicated to using GNS3 to emulate Cisco networks and Juniper networks, I found only a small amount of information about using GNS3 to emulate a network of Linux virtual machines running open-source routing and switching software. Our interest is to emulate networks of open-source routers and switches using open-source technologies.

GNS3 also supports other hardware emulation and virtualization technologies that can run Linux virtual machines: Qemu and VirtualBox. GNS3 supports Cisco router software images running on the Dynamips hardware emulation program. GNS3 is primarily used to emulate networks of Cisco routers and is used by professionals studying for Cisco certification exams. GNS3 is a very popular network simulation tool that runs on the major operating systems: Windows, Mac OS, and Linux.
