Can someone help?

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?

Please, a bit more details :

Did you apply xen patches to 2.6.31.5 ?
If yes from where they come ?

Boris.

Hmm.. dunno if this helps, it's from a user (from #xen) having problems with the
opensuse 2.6.31 patches:
