7 This document describes the virtual Trusted Platform Module (vTPM) subsystem for
9 Linux, and a basic understanding of the TPM and vTPM concepts.
18 of the vTPM's secrets (Keys, NVRAM, etc) are managed by a vTPM Manager domain,
20 these domains (manager, vTPM, and guest) is trusted, the vTPM subsystem extends
22 major component of vTPM is implemented as a separate domain, providing secure
23 separation guaranteed by the hypervisor. The vTPM domains are implemented in

115 Support for the vTPM driver was added in Xen using the libxl toolstack in Xen
116 4.3.  See the Xen documentation (docs/misc/vtpm.txt) for details on setting up
117 the vTPM and vTPM Manager stub domains.  Once the stub domains are running, a
