I first tried by reverting to the commit before this one, just like Jay
reported for https://bugzilla.kernel.org/show_bug.cgi?id=58941. But this
just varied the error (kvm reports an internal error), didn't solve the
issue. Now I simply reverted the commit on top of next, but without an
effect. Looks like those problems are not directly related.

Kashyap, you can do us a favor and try to find out if there was a commit
in the recent history (roughly before I started to hack on nVMX this
year) where this test cases succeeded.

TIA,
Jan
