Embodiments of techniques and systems associated with roots-of-trust (RTMs) for measurement of virtual machines (VMs) are disclosed. In some embodiments, a computing platform may provide a virtual machine RTM (vRTM) in a first secure enclave of the computing platform. The computing platform may be configured to perform an integrity measurement of the first secure enclave. The computing platform may provide a virtual machine trusted platform module (vTPM), for a guest VM, outside the first secure enclave of the computing platform. The computing platform may initiate a chain of integrity measurements between the vRTM and a resource of the guest VM. Other embodiments may be described and/or claimed.
