Perhaps we can enable it at compile time, so in production builds that
is disabled. It's not *that* much of a problem.

The purpose for this patch is that we can integrate the whole test suite
into kvm autotest, and we have ways to conveniently build qemu source
code, passing special flags to configure and everything.

So having this patch upstream at some point would make things easier,
since the folks at intel won't have to keep maintaining that patch for
every little change on qemu code, and we'll have better qa for qemu and
kvm.
