Virtualization has been a huge buzzword lately, but despite how much it can offer and how much players like AMD and Intel want businesses to pay attention to it, most people still have no idea how it works or what it could do. If you're wanting to know more, there is a great interview
with Andrey Savochkin, a software developer for OpenVZ, a virtualization suite. Savochkin talks about both the hardware and software methods of getting virtualization done, as well as key advantages that the technology in general gives.
While OpenVZ is strictly a software solution that directly competes with suites like Vmware, Xen, et cetera, the methods can apply to many environments. The interview is lengthy and fairly technical, but if you are into VT at all it's a great read. You can also learn more about the OpenVZ
project at their site.
