U R getting warm. From the document you referenced:

A virtual machine monitor (VMM, also known as a hypervisor)
consists of software that controls the execution of multiple guest operating systems on a single physical machine; the VMM
provides each guest the appearance of full control over a
complete computer system (memory, CPU, and all peripheral
devices). The use of the term host refers to the execution
context of the VMM. World switch refers to the operation of
switching between the host and guest.

Fundamentally, VMMs work by intercepting and emulating in a
safe manner sensitive operations in the guest (such as changing the page tables, which could give a guest access to memory it is not allowed to access). AMD’s SVM provides hardware assists to improve performance and facilitate implementation of virtualization.

Attestation. The SKINIT instruction and associated system
support (the Trusted Platform Module, or TPM) allow for
verifiable startup of trusted software (such as a VMM), based
on secure hash comparison.


(Sounds interoperable to me. IA Vanderpool works similarly.)

Page 11:

GVTPM Manager Suite

– Presented to TCG for consideration
– Create TCG Credentials for GVTPM Device Models that implement TPM 1.2 interfaces

– Roots the GVTPM Device Model’s trust in the hardware TPM
– Provides management of the TPM and its resources
