I think I am able to triage this issue, please have a look at the review post
with subject "[PATCH] ESX: Fix DISPATCH_FREE generation code to free all
extended objects".

Subject: [libvirt] ESX error while freeing inherited objects
Hi All,
Freeing of an object having inheritance depth >=2 throws an error such as:
" internal error Call to esxVI_<grand_parent>_Free for unexpected type 'Child'.
"
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!
Ata
