The other thing to consider is that CentOS 5 has Xen built right in,

performance penalty (only 2%-3%) (Para-virtualization). Otherwise, there
will be full-virtualization, and we should expect a performance loss
about 30% for each guest OS (like Windows).

I may be wrong but I thought that the guest OS kernel only needs special support if the underlying CPU doesn't have virtualization support which pretty much all the new Intel and AMD chips have. No?
