The Virtual Trusted Platform Module (vTPM) feature lets you add a TPM 2.0 virtual cryptoprocessor to a virtual machine.
A vTPM is a software-based representation of a physical Trusted Platform Module 2.0 chip. A vTPM acts like any other virtual device. You can add a vTPM to a virtual machine in the same way you add virtual CPUs, memory, disk controllers, or network controllers. A vTPM does not require a hardware Trusted Platform Module chip.
