" For instance: Below code snippet is from esx_vi_generator.input (modified) object VirtualDevice Int key r Description deviceInfo o VirtualDeviceBackingInfo backing o VirtualDeviceConnectInfo connectable o Int controllerKey o Int unitNumber o end object VirtualController extends VirtualDevice Int busNumber r Int device ol end object VirtualIDEController extends VirtualController end object VirtualDeviceConfigSpec VirtualDeviceConfigSpecOperation operation o VirtualDeviceConfigSpecFileOperation fileOperation o VirtualDevice device r end object VirtualMachineConfigSpec . . . VirtualDeviceConfigSpec deviceChange ol . . end On free of "VirtualMachineConfigSpec", I hit below error: " libvir: ESX Driver error : internal error Call to esxVI_VirtualDevice_Free for unexpected type 'VirtualIDEController' " But if I remove VirtualController and include its fields directly to VirtualIDEController, error is resolved. Please let me know if I'm missing anything, else, it seems like a bug with generated code. While debugging the error seems to come from: esx_vi_types.c: /* * Macros to implement dynamic dispatched functions */ #define ESX_VI__TEMPLATE__DISPATCH(_actual_type, _actual_type_name, __type, \ _dispatch, _error_return) \ switch (_actual_type) { \ _dispatch \ \ case esxVI_Type_##__type: \ break; \ \ default: \ virReportError(VIR_ERR_INTERNAL_ERROR, \ _("Call to %s for unexpected type '%s'"), \ __FUNCTION__, _actual_type_name); \ return _error_return; \ } Thanks!
