NEM/win: Added concern about emulating VMMCALL/VMCALL. bugref:9044

File:

trunk/src/VBox/VMM/VMMR3/NEMR3Native-win.cpp

-              r72419
+              r72420
+ *
+ *
+ * - To handle the VMMCALL / VMCALL instructions, it seems we need to intercept
+ *   \#UD exceptions and inspect the opcodes.  A dedicated exit for hypercalls
+ *   would be more efficient, esp. for guests using \#UD for other purposes..
+ *
+ *
  * - Wrong instruction length in the VpContext with unmapped GPA memory exit
  *   contexts on 17115/AMD.
