There are few technologies in the data center that are getting the same level of attention from enterprises as virtualization.
Virtualization offers the promise of driving down costs through consolidation while increasing server utilization. The technology also is rapidly expanding beyond servers and into other aspects of the data center, from storage devices to applications to networks.
Sun has virtualization for its SPARC hardware running Solaris and also for commodity x86 systems in its xVM line. IBM has virtualization for its proprietary hardware and would likely add the xVM developments to its product line while phasing out Sun's proprietary virtualization system as the underlying hardware reached the end of its service life.
Sun acquired Innotek-the original maker of VirtualBox-in February 2008, so it isn't as if IT managers have had years to implement and embed the x86 virtualization technology. As a competitor to Microsoft's Hyper-V or, more importantly, VMware's ESXi, it doesn't really register on the scale.
IBM has relationships with VMware and embeds the VMware hypervisor in some of its server offerings. Leaving IT managers undisturbed as they proceed to virtualize with VMware would probably have the advantage over an attempt to introduce xVM.
