>     *INTRODUCTION*
> ========================
> The goal of virtual Trusted Platform Module (vTPM) is to provide a TPM
> functionality to virtual machines (Fedora, Ubuntu, Redhat, Windows .etc). This
> allows programs to interact with a TPM in a virtual machine the same way they
> interact with a TPM on the physical system. Each virtual machine gets its own
> unique, emulated, software TPM. Each major component of vTPM is
> implemented as a stubdom, providing secure separation guaranteed by the
> hypervisor.
> 
> The vTPM stubdom is a Xen mini-OS domain that emulates a TPM for the virtual
> machine to use. It is a small wrapper around the Berlios TPM emulator. TPM
> commands are passed from mini-os TPM backend driver.
