Introduction to the Xen Virtual Machine

vivek, Fri, 2005-09-02 18:57

Xen is the new kid in the virtualization arena, receiving well deserved attention from the industry and the academia, with some really big players betting on it.

Xen is an open source virtual machine monitor, or hypervisor, developed by the University of Cambridge. It has a design goal of being able to run 100 full featured OS instances on a single typical computer. Xen provides secure isolation, resource control, quality of service guarantees, and live migration of virtual machines.

Linux Journal is featuring an introductory article on Xen and its design. A nice, moderately technical read: Introduction to the Xen Virtual Machine

Ok, I am not so good at linux and all lin/uni stuff. So basically i had to read through many available xen informational pages before understanding it. In the wiki web, it was exclaimed that IBM mainframes use Virtual Servers or hypervisors to increase work efficiency, inter OS communication and processing power management. OK I understood upto that. But if it runs multiple processes on different OS and when it comes to load balancing or clustering, how does it manage with redundancy? I mean, if the work load is distributed on multiple OS, and if one fails on a single OS, how does the clustering work on others? Got any info on that? Also does it have any potential use to global public users except for MNC's?
