ABSTRACT:
In one embodiment, the present invention includes a method for receiving a request for a trusted platform module (TPM) operation from a virtual machine, determining whether the request is for a modification of a TPM version, and associating part of a multi-context hardware TPM with a virtual TPM (vTPM) to enable the modification. Other embodiments are described and claimed.
