I am interested in virtualization related projects. However there seems to be plenty of options in this field. Which project should i start working on given the above choices. I want to work on on of these projects going forward. I am familiar with the basics of virtualization methods available and basic interfaces. Have been using VirtualBox for more than 3 years now.

Answer 1

First, ask yourself what type of code you want to contribute. If it is more on the binary-translation side, your best choice is QEmu since it does all the core work for KVM. KVM on the other hand, is an architecture that sits upon QEmu and leverages the Linux kernel's scheduler. So if IPC, process management, signals etc are your thing, jump into KVM. i would suggest that you study the architectures of these hypervisors and then decide what you want to get into.

This was a specific example. Virtualization is much more than hypervisors. Look into OpenStack. It is to virtualization what Android is to smartphones.

Another interesting thing to look into, to begin coding would be libvirt. It is the underlying library that powers most of hypervisor-agnostic virtualization frameworks and orchestration tools.
