This has been the buzz word of the year, touching various platforms, hardware and applications although it has been in existence since 1960 during the mainframe era. In simple terms, it enables abstraction of any of the computing resources that can dynamically share each other across multiple environments and even remotely in a virtual infrastructure.
Operating System virtualisation enables multiple platforms in a single hosting environment. Application virtualization, hosts individual applications in different or even remote hardware/software and they are made accessible through a simpler interface from a range of devices including conventional desktops and smart phones.
By virtualisation there is high availability of resources, and the resource complexity is hidden for practical purposes. Performance is greatly enhanced with memory and storage virtualisation and so there is better utilisation, increased security, and improved disaster recovery facilities.

I happened to stumble on your blog sometime back and i did read this post on virtualisation, I am impressed by the variety of content that you gather.
By the way have a look on my post on virtualisation, i am attempting to make it simple and also outline clear the concepts but i end up having everything

I could not view the video as javascript was not enabled on my laptop.
better luck nexttime...
