With the inclusion the of these technologies, the linux kernel provides researchers an environment where they can play around with various techniques and advance the state of the art in Virtualization. I look forward to a future where nearly all the innovations to virtualization will come not from proprietary platforms like MS Virtual PC or VMware but from opensource hypervisors. Linux has played a key role in the past in advancing Virtualization. VMware was one of the first full virtualization solutions and start the revival of the virtualization market, however it was an open source virtualization hypervisor Xen, which actually managed to introduce a software which allowed near native performance virtualization. It was again Xen, which provided support to hardware assisted platforms like Intel VT and AMD SVM.
