Virtualization of linux based computers : The linux-VServer project

Abstract

This article presents the available programs that can provide, with different technology, a virtualization of Linux computers. We will define some usage criteria that will allow the reader to chose the relevant virtualization technology according to its specific needs. In the second part of the article we will focus on the Linux-VServer technology, which is a very lightweight and effective technology for the regular Linux user not interested in Kernel hacking. The Linux- VServer project also supports additional security options and resources limitation that can be very useful. This is also the most mature open-source technology and several users have production servers using this technology for years now. © 2005 IEEE.
