In this nice “state-of-the-union” article about KVM and its position in the general Linux and open source marketplace, the author talks about one of the key differences between KVM and other virtualization technologies — such as VMware and Xen — that KVM’s code has been entered into the Linux kernel code.

This makes KVM a very interesting technology to keep your/our eyes on… but, despite getting some good press lately, it seems that KVM won’t be ready for primetime for 1-3 years (depending on who you believe in the article).

Suffice to say that while there are some great technical developments (generally) in the world of virtualization, there’s still much work to be done.  Thankfully, Xen and VMware are available now and ready for use, so you can start realizing the advantages of virtualization in the data center sooner than later.
