Hi Roger, Thank you very much for looking into the issue. Can I have a SVN version of the patch? "patch" does not seem to like the diff (or maybe I am using it incorrectly) root@fxen1:/usr/src # patch -n < ~/xen_hyperv.patch Hmm... I can't seem to find a patch in there anywhere. root@fxen1:/usr/src # Regards. @shankerbalanhelp
