Xensource is using 2.6.18 (RHEL5) in their own commercial product, so that's
why they're focusing xen kernel development on that version.. 

Xensource tried getting xen patches integrated into upstream linux earlier, 
but it didn't succeed (too big changes?) and kernel developers decided 
they need to create this common "pv_ops" framework for running paravirtual 
linux on hypervisors.. 

So that has taken some time.. and only recently (some) xen features have been ported to
this pv_ops framework and integrated into vanilla kernel.. more features are being ported.

So yeah.. atm the xen/dom0 kernel situation is a bit shitty.. 

pv_ops (VMI) paravirtual linux kernels are also supported by VMware.
