From 8cda3b02882b6c2b398dffdd8533f2135e9cb088 Mon Sep 17 00:00:00 2001 From: Paul Durrant Date: Wed, 22 Aug 2012 22:26:27 +0100 Subject: hvm: Remove VM genearation ID device and incr_generationid from build_info. Microsoft have now published their VM generation ID specification at https://www.microsoft.com/en-us/download/details.aspx?id=30707. It differs from the original specification upon which I based my implementation in several key areas. Particularly, it is no longer an incrementing 64-bit counter and so this patch is to remove the incr_generationid field from the build_info and also disable the ACPI device before 4.2 is released. I will follow up with further patches to implement the VM generation ID to the new specification.
