This would work, but installing to /usr/include/linux/kvm.h will confuse
distro package managers a lot, because that location belongs to the glibc
or libc-linux-headers or some other package already.
If you want to install the headers from kvm-kmod, I would recommend
doing it in a different path, e.g. /usr/include/kvm-kmod/{linux,asm}.
qemu can then add -I/usr/include/kvm-kmod to it's default include
path and get the kvm-kmod version if that's installed or the distro
version otherwise.
It may also be useful to do the equivalent of 'make headers_install'
from the kernel, to remove all "#ifdef __KERNEL__" sections and
sparse annotations from the header files, but it should also work
without that.
