'OSError: [Errno 38] Function not implemented' for python command 'asyncio.get_event_loop ()'

This post was originally published on this site


I do not know if this is a bug or such a feature of ESXi 6.5, but I decided to write on the forum. The bottom line is that on ESXi 6.5, if you run the following commands in python, we get an exception:

>>> import asyncio

>>> loop = asyncio.get_event_loop ()

Traceback (most recent call last):

AttributeError: ‘_UnixSelectorEventLoop’ object has no attribute ‘_ssock’

This works for ESXi 6.7 and ESXi 7.0

Command result of ‘esxcli system version get’:

   Product: VMware ESXi
