contains code that allows to at least detect local migration of a virtual machine and handles this for the virtual TPM (results in a no-op for local migr.). If migration of a virtual machine with attached vTPM to another machine is attempted, XenD will return an error. Signed-off-by: Stefan Berger <stefanb@us.ibm.com>
