Hello

I am trying to compile kvm-kmod-devel-88.tar.gz with 2.6.31. Seems there is a missing header file.

vger kvm-kmod-devel-88 # make

make -C /lib/modules/2.6.31-gentoo/build M=pwd \

                LINUXINCLUDE="-I`pwd`/include -Iinclude \

                -include include/linux/autoconf.h \


                -include `pwd`/x86/external-module-compat.h " \


                "$@"

cd kvm-kmod
git submodule update --init

make

still the same error.

is there a patch for 2.6.31 support?

This should fix it:

---------->

This unbreaks 2.6.31 builds but also ensures that we always use the most recent one.

so i backed out the original patch and applied your new patch to devel-88 instead.

ok it compiles but now I get unknown symbols warnings below. this occurs with or without --kerneldir.

Ah, my fault. That's because your 'origin' is now kiszka.org. Go to kvm-kmod/.git/config and update the submodule url to
git://git.kernel.org/pub/scm/virt/kvm/kvm.git. Then do a 'git submodule update' and proceed with the other steps.

so i backed out the original patch and applied your new patch to devel-88 instead.
ok it compiles but now I get unknown symbols warnings below. this occurs with or without --kerneldir.

I think (hope) that this is due to issues which are fixed in latest kvm-kmod. Let us try to get the git version running first as it shall be released as kvm-kmod-2.6.31 soon.

Hi Jan
ok thanks (sorry, new to git).
unfortunately, still getting the mmutrace.h failure (same error without kerneldir):

[...]

OK, there was more git foo hidden behind "clone my tree": Once you cloned it, you are still on the master branch. You then have to checkout that 'queue' branch I was referring to:

.../kvm-kmod> git checkout -b queue origin/queue

Now you have to run 'git submodule update' once again as my queue uses a different revision from kvm.git. But then everything should really work.

Aidan, were you able to solve this? I was having the same (original) problem in Xubuntu 64-bits with a custom 2.6.31 kernel and kvm-88. I still haven't tried Jan's patch (paper deadline at work) but I wanted to know if you had made any progress.

Cheers,
Jorge

The kvm-kmod tree at git://git.kiszka.org/kvm-kmod.git (branch 'queue') meanwhile contains patches that solved all Aidan's build problems.

But note: Even your customized 2.6.31 contains the very same KVM kernel sources my tree is currently pulling in. So you could make your life easier by simply compiling them along your kernel.

The kvm-kmod patches will become important again when we pull more recent KVM sources that are not yet part of the latest kernel, at least not part of the particular kernel one is forced to use (for whatever reason).

Do not meddle in the internals of kernels, for they are subtle and quick to panic.
