linux.inet.hr — The upcoming 2.6.20 Linux kernel is bringing a nice virtualization framework for all virtualization fans out there, KVM, short for Kernel-based Virtual Machine. This article tries to explain how it all works, in theory and practice, together with some simple benchmarks. While still in the early development stages, KVM shows a real potential.

It might have been nicer if they had chosen an acronym that didn't already exist. When I hear KVM I automatically think of a KVM switch which can be defined as follows for those of you unawares..."A Keyboard, Video, Mouse (KVM) switch allows a single keyboard, video display monitor, and mouse to be switched to any of a number of computers when typically a single person interacts with all the computers but only one at a time. The switch provides more table space in addition to saving the cost of multiple keyboards and monitors."

Yeah, all I did was double click on the VMware setup.exe, configure virtual machines, and now I have 20 servers spread out amongst 8 physical servers. If one of those physical servers goes bad, I click a button and my VMs magically move to another physical server. It's nice that KVM "shows some potential" ... but up here in 2006, we're busy working with products that are already done. EDIT: Stupid abbreviation too.

@felderado"and the big boys by VMWare like their ESX products run on........ *drumroll*.... LINUX"*drumroll* ..... WRONG. VMware ESX/Infrastructure runs on a proprietary kernel which is not based on Linux and uses it's own native file system. A Linux virtual machine is used for console access to administer the system. The only other Linux that's built in is simply used as a boot loader, sitting in the same corner that DOS sat in with Windows 95.VMware ESX is NOT Linux based. Please don't perpetuate this lie.

For anyone reading this now, which I sincerely doubt, I am now a full time Ubuntu user. I've got it on my desktop and laptop, and I'm now convincing people that it is in fact user friendly, and to try it out.Amazing what can change in just over a year!
