Subject: [PATCH] libxl: allow to enable/disable cpuid bits
Date: Tue, 1 Nov 2011 12:03:28 +0100 [thread overview]
Message-ID: <4EAFD200.4010207@amd.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 567 bytes --]
Allow to enable/disable SVM specific cpuid bits
in the guest config file via cpuid config option.
Also allow to enable/disable the hypervisor cpuid bit
in the guest config file. We need to disable the
hypervisor cpuid bit to get Hyper-V going.
