To run virtual nodes in a simulated network, the GNS3 open-source network simulator supports two virtualization technologies: Qemu and VirtualBox. The open-source routers we will use in a GNS3 simulated network must run on either a Qemu or a VirtualBox hypervisor. Depending on one’s requirements, one might choose either VirtualBox or Qemu. Let me tell […]
I’ve been using Parallels Desktop for Mac to run a Debian Linux 6.0 virtual machine. I wanted to install the Parallels Tools in the Debian virtual machine so I could take advantage of better integration between the Linux virtual machine and the Mac OS X host computer. It wasn’t as straightforward as I thought it
A network of virtual machines can be used for practical testing and research. Sandia National Laboratories recently announced that they have created a virtual network of three hundred thousand virtual machines, each of which is running the Android operating system, on a single large supercomputer. In the recent past the researchers at Sandia National Laboratories
In this article, we will review the procedures required to install Debian Linux in a virtual machine managed by the VirtualBox application. A summary of the procedures is listed below: Download the Debian install DVD. Create a virtual machine using the VirtualBox application. Boot the virtual machine from the DVD image we downloaded Install the
I am building a virtual machine that will run the open-source network simulation tools that I want to research. There are good reasons to use a virtual machine for these experiments, even if software running inside a virtual machine may run slightly slower than software running on a native host. Below, I list the benefits
I chose to look at the NetKit network simulation tool first for two reasons: NetKit has an adequate number of lab scenarios ready to use and it is available as a bootable disk image, which makes it easy to just try it out. Because I wanted to keep things simple and avoid repartitioning my hard
NOTE updated February 26, 2013: This post contains old information. I created a page that lists all the open-source network simulators listed in the post below. I will keep the page up-to-date. Please see the List of Open-Source Network Simulators page. I am impressed with the number of network simulation tools available as open-source software.
