From a93027461d7585c35f9b93235a3a06f5114dcf52 Mon Sep 17 00:00:00 2001 From: "kfraser@localhost.localdomain" Date: Fri, 29 Sep 2006 11:21:02 +0100 Subject: [PATCH] [HVM][SVM] 64-bit Windows HVM guests require MCE/MCA CPUID bits to be present. This SVM patch removes "masking off" of these bits for AMD-V HVM guests.
