Reference: link

Following the assignment of memory and VCPU resources, the host can transition the guest into a TVM_RUNNABLE state by calling sbi_covh_finalize_tvm(). The host must set up TVM Boot vCPU execution parameters like the entrypoint (ENTRY_PC) and boot argument (ENTRY_ARG) using arguments to sbi_covh_finalize_tvm(). Note that some TEE calls are no longer permissible after this transition.

host calls? The TEE cannot even run before the TVM has been finalized
