Hi Fajar,
I am using LV backed domUs in PV currently. I would like to maybe explore HVM in future though so I'd like that option to remain open.
Other than that, I'm not using VT-d or anything along those lines, so nothing majorly fancy.
So if I grab the F16 kernel, recompile the RPM under CentOS 6.x, this should be OK for dom0 use?
Were there any catches, ie. other utils eg. udev and the likes that needed to be updated before you could boot the F16 kernel?
Regards,
Alan

That's the tricky part.
While RHEL5 have dom0-compatible -xen kernel, RHEL6 only has
domU-compatible kernel.
My personal preference is what I mentioned above: use latest vanilla
kernel, packaged as RPM. At least that way when a new vulnerability
comes out you just need to recompile the latest kernel plus whatever
Linus-blessed emergency-patch available. The downside, you won't have
blktap support (which shouldn't matter if you use LV-backed domUs).
Others might opt for the more-tested 2.6.32 xen-pv_ops though. At
least Oracle VM also uses kernel 2.6.32.
