Just want to drop this note, so no one else gets bother with my query. I was able to find the reason and its fixed. It seems one of the ENUMs deep inside one of the structures was not defined. I am not sure if single step is the only way to solve such issues, as ESX_VI_ERROR never provided any useful information. Thanks!

I am using hostSystem object (propertyNameList is set to “config.storageDevice.hostBusAdapter”) to retrieve list of “HostHostBusAdapter” from ESX, but the call fails to perform “CastFromAnyType” from ObjectContent –> HostHostBusAdapter. The esx_vi_generator.input object definition looks like this: object HostHostBusAdapter String key o String device r Int bus r String status r String model r String driver o String pci o end esx_vi_generaor.py is modified as follows: "HostHostBusAdapter" : Object.FEATURE__ANY_TYPE | Object.FEATURE__LIST, Using gdb, I see the failure occurs at: esx/esx_vi.c:esxVI_List_CastFromAnyType(..) line 1631: .. if (esxVI_AnyType_Deserialize(childNode, &childAnyType) < 0 || castFromAnyTypeFunc(childAnyType, &item) < 0 || esxVI_List_Append(list, item) < 0) { goto cleanup; } .. In one of my earlier patches (subject: Add routines to interface driver) I patched esx_vi_generator.py to deserialize “string list”; as the patch is still under review I manually applied the branch to this branch but no change (did not expect change as structure does not contain any list object). I am wondering what else is missing to make it work. Any suggestion how to debug/fix this issue is highly appreciated. Thanks!
