The InfiniBand Architecture (IBA) is technology from intel. It increase performance on Intel® Xeon™ and Intel® Itanium® processor platfrom

And z/VM hypervisor are VM technology base on IBM server platfrom only.

 

If you want/need use VM technology in another platfrom. You wait for Xen technology. I hear some information the RH and Debian comminity include the Xen technology into own distro. (FC5 include Xen technology into kernel ) If you want use Xen before the others. It's need patch the kernel.
