描述

Hi folk, I try do use python multiprocessing module to parallelize some data gathering from vcenter. Unfortunately i have faced with following problem during starting parallel processes:

_pickle.PicklingError: Can't pickle <class 'pyVmomi.VmomiSupport.vim.VirtualMachine'>: attribute lookup vim.VirtualMachine on pyVmomi.VmomiSupport failed

So the question is, it's that true, that pymomi doesn't support "right pickling"? Thanks, and appreciate.

研究方向
The issue involves a PicklingError when using multiprocessing with pyvmomi classes like vim.VirtualMachine. To resolve, one could implement custom getstate and setstate methods in the relevant classes. Review the pyVmomi source code, especially VmomiSupport.py, to understand the class structure and identify where to add pickling support. There are no existing PRs or comments suggesting a solution; maintainers should discuss the best approach.
