With hexacore CPUs, fast memories, SSDs, NICs available for desktops, I guess the gap is getting narrower. And IIRC, the article is about desktop class hardware ;) > Also, last I checked, which was some time in Oct 2010, there were also > restrictions on adding machines with heterogeneous CPUs to a server cluster > (If this has changed, I would love to be updated).

Thanks to paravirt_ops[1] kernel support which was present in Linux kernel since 2.6.23, you can use same kernel to boot as dom0, domU, or without Xen. I've never used VMware ESX (nor I intend to), but from what I heard it's more like a virtualization OS made to run on bare metal, unlike Xen which doesn't restrict you in this way, so you can use dom0 for different purpose.
