There aren't the real kernel headers, just cheap copies carried in qemu-kvm.git which have been appropriately postprocessed. We do this since the kvm external module can run on a much older kernel, so there is no natural place to find it headers.

Sorry for the confusion on my part. I was aware of the sanitized
kernel headers, but was mislead by the line

kerneldir=/lib/modules/$(uname -r)/build

in kvm/user/configure. What I didn't realize is that this
always gets overridden by kvm/configure.
Maybe we can change the default in kvm/user/configure to
something more sensible:

[PATCH] kvm: user: fix default kerneldir

calling ./configure in kvm/user sets the kerneldir to the
currently running kernel, which is incorrect for user code.
This changes the default to the sanitized header files from
the kvm/kernel directory.

I usually add a readlink -f in there due to my innate fear of relative directories and cd.

btw, these are my plans for kvm/user:

- convert the tests to be loadable with qemu -kernel; we lose the simplicity of kvmctl so I'm not 100% sure it's a good idea. On the other hand some of the tests are useful for tcg. - kill kvmtrace (replaced by the standard ftrace tools, whatever they are; maybe create a new repo if kvm specific tools are needed)
