Xen, VmWare, or as a matter of fact KVM, are for X86 architectures. In IBM Power systems where all/most implement logical partitioning at the hardware (CPU) level, you can install any Power compatible os (RHEL/SLES/Debian, etc.) in each individually carved logical partition. The newer Power6 can even emulate x86 environments where you can install your own X86 based operating systems; yes, even those of an proprietary nature --like the ubiquitous family from the monopoly. Evidently, when x86 server sprawl starts to get out of hand (or even before that, if you are in an proactive organization), consolidating your IT resources into IBM Power6 systems will simplify your systems management. These latter systems scale much better for, besides possessing CPUs multiple times faster than the best current X86 offering, their overall architecture has been designed with the enterprise needs in mind --along with cost effectiveness in the long run since these architectures implement energy management functions by design, for instance. The low end of IBM Power6 are even well within the budget of small and medium business organizations that regard IT assets as an long term investment in themselves. Load balancing, migrating, or failover of logical partitions and live virtual machines containing critical business resources in enabled IBM Power systems environments is nothing to make a media hype about. Oh, an afterthought on x86 architectures, Mark. IBM researchers were working on an version of KVM "...that will not require [x86] hardware virtualization support."[*] Hence, if that effort is successful, KVM would be on an equal footing with Xen and would be in an serious position to challenge Xen for prominence/adaptation to the current Cloud Computing paradigm. The open source unrestricted access, and multiple independent implementations by so varied free/open/hybrid commercial vendors of these open source technologies give them an edge over what VmWare or MS HyperV can offer.
