It's clearly not the most friendly error message, but I debugged it, you just have to specify the right version for VMSTATE_STRUCT_ARRAY: 0. VMSTATE_STRUCT_ARRAY(loc, TPMState, TPM_TIS_NUM_LOCALITIES, 0, vmstate_locty, TPMLocality), Then it all works with version 0 (or default value) thanks > > It must have something to do with the nesting invoked by > VMSTATE_STRUCT_ARRAY(loc,...) below. > > > > >> >> >> >>> + .pre_save = tpm_tis_pre_save, >>> + .fields = (VMStateField[]) { >>> + VMSTATE_BUFFER(buffer, TPMState), >>> + VMSTATE_UINT16(rw_offset, TPMState), >>> + VMSTATE_UINT8(active_locty, TPMState), >>> + VMSTATE_UINT8(aborting_locty, TPMState), >>> + VMSTATE_UINT8(next_locty, TPMState), >>> + >>> + VMSTATE_STRUCT_ARRAY(loc, TPMState, TPM_TIS_NUM_LOCALITIES, 1, >>> + vmstate_locty, TPMLocality), >>> + >>> + VMSTATE_END_OF_LIST() >>> + } >>> }; >>> >>> static Property tpm_tis_properties[] = { >>> -- >>> 2.5.5 >>> > > -- Marc-André Lureau
