XenServer results from the Test Day for RC2

Hi,

While attempting to test Konrads new interrupt injection logic, I got
blocked behind yet another Pygrub bug caused by c/s d1b93ea

This is the first time I have looked into the issue, but a cursory
inspection of the first hunk shows that it cannot possibly be correct as
self._default is either an integer or string.

I have a possible workaround which I am testing, but cursory review of
the patch would have shown that it cannot work as intended.

Notice that self._default is now either a string or an integer,
defaulting to an integer, and the top level code is updated to require a
string.  As a result, any bootloader configuration which doesn't
explicitly set a default, or still drives this logic with integers
(ExtLinux or LiLO) will die with an AttributeError
