That page mentions a special xen patch package and manualy applies
that to a vaniall kernel. I'm building from a linux-2.6 source
snapshot where xen should be already included. But that seems to work
different from that patch package.

How does it know to build a 32bit or 64bit kernel? I want the later.


mrvn at storage:~/kernel/linux-2.6-2.6.15+2.6.16-rc5$ make-kpkg --revision 2.6.15+2.6.16-rc5-0experimental.1snapshot.6056 --append-to-version .6-xen --arch xen kernel_image
 I note you are using a hyphen in the revision number.
 Please ensure that the upstream and debian revision
 numbers are policy compliant enough that dpkg and
 shall not choke on them at the end of the compile

This is a freshly unpacked
linux-2.6_2.6.15+2.6.16-rc5-0experimental.1snapshot.6056.dsc that
builds a xen kernel image (among all the others) just fine with
debuild.

I looks like I fist have to apply
debian/patches/xen-tree-merge-21940.patch, set CONFIG_X86_64_XEN and
then just build for arch x86_64. Is that right?

The only problem then is that make-kpkg will put the wrong image into
the deb (the one with bootsector instead of the raw image) unless I'm
mistaken. If that is so I can figure out the rest. I've messed with
make-kpkg before.

PS: Or should I scratch that and stick with the unofficial
linux-patch-xen?
