Tux Machines (TM)-specific
In spite of currently having a very small user base, Kernel-based Virtual Machine (KVM) is getting quite a bit of attention lately from the press and the virtualization market.
VMware still soundly dominates the market as well as the majority of the media discussions, but Microsoft Hyper-V is starting to pick up steam in both areas. Xen, on the other hand, has been around since 2003, and companies like Citrix and Oracle hope to make great strides leveraging this technology for their own purposes. But KVM is the newcomer here, and it has a long stretch of road ahead of it to catch up with these other technologies. It does have one thing going for it, however: The KVM technology is integrated into the Linux kernel.
Red Hat continues to be the main champion and major contributor of the commercial implementation of KVM, but it could be getting some help from some very unfriendly places.
