Last vendor entering the virtualization arena is the german company innotek.
They launched an open source desktop virtualization product called VirtualBox in January 2007, but besides that the company mostly runs in stealth mode. In fact VirtualBox didn’t get much traction over the year, given the hard competition with VMware Player and Workstation, Microsoft Virtual PC and Parallels Workstation.
Anyway innotek is much more interesting for another product, a true bare-metal hypervisor with microkernel architecture, that is in development since a while: hyperkernel.
At today there are no public informations (tech specifications, features, release dates, etc.) about this possible competitor for VMware, Microsoft, Citrix and all the others, but the launch date may be near: the official website now exposes a very short statement saying the product is currently in use by selected customers, despite not yet generally available.
This leads to think innotek reached private beta for its new hypervisor and we may see an official launch in 2008.
