Developing OpenSwitch With Linux VM/OS X Host

Deprecation notice: this blog has moved to http://opennetgeek.github.io. Please use that URL to find the latest articles.

One of the purposes when we designed the build system in OpenSwitch, was to make it possible to develop on as many environments as possible. If you have some background with developing networking firmware, the typical developer love to have this VM where everything works perfectly, but makes it impossible to work in your laptop at 30000 feet. This is not really a sin (as long as you can have the VM hosted in your machine), but the problem is that usually is some IT team on charge of the VMs setup, and the deployment is not handled by some automated/version-controlled code.

So for OpenSwitch, we aimed to at least document the requirements and steps for manual setup of your environment. You can read this page to get your Linux machine to ready it for OpenSwitch development.

So, why to write an article about my particular setup? Well, I’m a Mac user, so in this article I’m going to detail my setup using a OS X host with a Linux VM. This provides some nice tricks that makes your workflow easier if you are using a similar setup. I will also explain the rationale of the setup.

My use of Linux VM for development is mostly thru the Linux CLI and I use NFS to share files between my Mac and Linux. This allows me to use any graphical tool from the Linux VM if I have to, but also to use tools from the host without major hurdles. Continue reading Developing OpenSwitch With Linux VM/OS X Host
