Hi Jeroen,
thanks a lot for your testing!

That explains why I'm not seeing it. You're running on x86_64 and I on
i386. The attached patch should fix your problem - I can't test that
here since I don't have a 64bit capable machine around.

I can only assume the error got ignored in earlier versions. The real
cause of the problem seems to be the version in Lenny. I'd be great if
you could check the attached patch.

There could be more bugs lurking though if you're not running on real
hardware since /dev/kvm isn't available then, but in this case the more
detailed error message should give us another hint.
