Thanks, please submit it in the form describe in the wiki page
http://wiki.xen.org/wiki/Submitting_Xen_Patches which I referenced
before.

In particular, a Signed-off-by is a strict requirement for licensing
reasons, to indicate that you have read the DCO (which is at
http://wiki.xen.org/wiki/Submitting_Xen_Patches#Signing_off_a_patch ).

Please also provide a suitable changelog entry and use a unified diff
(diff -u).

I think rather than "[-]*" the right addition would be -? (i.e. a single
optional negative sign), unless Python's re syntax is lots different to
what I expect.

These fields are unsigned int, .i.e. always 32-bits. So I think your "if
self.conf < 0: self.cons = 4294967296 + self.cons" etc will work. The
Internet also suggests "ctypes.c_uint32(i).value", dunno if that is
better. In any case writing 4294967296 as 2**32 would be slightly
clearer.
