Currently, Linux hypervisors, Xen and KVM, can only run on chips from Intel and AMD. IBM is working to add KVM support to the Power architecture by 2014. The company has already implemented this in development systems and its code has currently reached engineering level quality.
It is expected that vendors will be deploying KVM for the power architecture in their enterprise distribution come next year. KVM has mustered strong support from the Open Virtualization Alliance and were it to become the the industry standard in the hypervisor industry it would offer strong competitions to XenServer (Citrix), Azure (Microsoft) and VMware ESX.
