On installing Vista Ultimate on KVM I encountered some the project name is Linux-VServer and I hope that answers your question, if not, the technology is based on OS level virtualization, which means it uses a shared kernel, instead of virtual machines as long as Windows(tm) doesn't use a Linux kernel it won't be supported :) the advantage of OS level isolation/virtualization is that you only need a fraction of the resources than for full virtualization, which allows you to run hundreds of guests inside a recent machine best, Herbert > problem.
