I took the patches from http://code.google.com/p/gentoo-xen-kernel/downloads/list

I first downloaded the Ubuntu Kernel Source - Plain Vanila 2.6.31, Patched the kernel with Ubuntu patches - This gives you kernel 2.6.31-4 ubuntu style, then apply Kernel patch 2.6.31.4-5 from http://www.kernel.org/pub/linux/kernel/v2.6/incr/patch-2.6.31.4-5.bz2

Then I patch using the http://gentoo-xen-kernel.googlecode.com/files/xen-patches-2.6.31-7.tar.bz2 to be xen based kernel

Compiled the Ubuntu Way - Got kernel image 2.6.31-5-server-xen - dom0.

Minor changes was need to be change in the orig /xen-patches-2.6.31-7.tar.bz2 file to be compatible with my kernel.

I compiled it twice one for Dom0 and one for DomU with the relevant CONFIG_XEN settings.

I used xen-3.4 for the hypervisour, and apply the fix for grub2 issue with XEN (http://www.sourcemage.org/HowTo/Grub2WithXen)

It looks OK with minor issue on the DOMU complain about PCI space access error. - I still try to figure out what is the problem.

I also disabled the RTC in the domU compile settings and DMI scanning and all the Xen/paravirt_ops settings - since he are using old style here.

I'n not sure - if this is the best way to go, since I still try to understand what is the use of kernel-2.6.18.hq.

What is the different between kernel-2.6.18.hq. to the orig file at http://bits.xensource.com/oss-xen/release/3.4.0/linux-2.6.18-xen-3.4.0.tar.gz. Does the new options like PVUSB include in this file?

And Does the novel patches include new options like PVUSB for example?

I'm just checking -- does anyone know if the current Ubuntu release (9.10 Karmic Koala)
contains the necessary Xen kernel bits to be used as a DomU without patching?

I think he was asking if 9.10 had support for Xen and I'm fairly certain the answer is no. Intrepid didn't either which is why some of us use Debian kernels in our DomU Ubuntus.

Your only other choice is to run it as an HVM DomU.
