Hi Jan,
I'm trying to use your kvm-kmod git repo to build KVM git master
against the latest two Fedora 18 kernels (3.7.9-205 and 3.8.1-201),
and I'm running into a bit of trouble:
$ ./configure --kerneldir=/lib/modules/3.7.9-205.fc18.x86_64/build
$ make sync
$ make
make -C /lib/modules/3.7.9-205.fc18.x86_64/build M=`pwd` \

Looks like I'm getting hit by the kernel Makefile's "-Wall" flag. Even
worse, after I upgraded my Fedora machine's kernel to 3.8:
$ uname -a
... 3.8.1-201.fc18.x86_64 #1 SMP ... x86_64 x86_64 x86_64 GNU/Linux
and modifying the max_kernel_version in kvm-kmod's configure script:
$ sed -i 's/max_kernel_version=7/max_kernel_version=8/' configure
Things get even more complicated:
$ ./configure
$ make sync
$ make
make -C /lib/modules/3.8.1-201.fc18.x86_64/build M=`pwd` \
LINUXINCLUDE="-I`pwd`/include -Iinclude \

At this point, if I add e.g. "-I/usr/include \" to LINUXINCLUDE for "all:",
I get past that error, but get hit by the kernel Makefile's -Wall once again:

I'm wondering if there's something missing from the "sync" script (such
as a set of include files that would satisfy the above warnings, and the
"missing" asm/types.h in 3.8.*) ?
Thanks for any ideas,
