The next major production release of Ubuntu — version 8.04 LTS, codenamed Hardy Heron — will ship with KVM as its virtualization package. This choice is surprising to those of us who have been watching the Xen virtualization package become the darling of Virtual Machine world. So let’s try to make sense out of the KVM virtual machine and this recent choice by Ubuntu.
Understanding the Basics
For those of you new to virtualization, the landscape of virtual machine, or VM, technology is a bit of a jumble. For instance, below is the list of technologies that describe themselves as virtual machines:
* Application Virtualization
o Java
o Microsoft Dot Net CLR
o YARV
o Parrot
o Wine
* System Virtualization
o VMware
o Parallels
o Virtual PC
o VirtualBox
o Xen
o Solaris Zones
While application virtualization runs programs written for specific languages, system virtualization runs operating systems. What is the difference between these two systems and ultimately the distinction that made Ubuntu choose KVM over Xen?
