Title:
nova-compute in down state (servicegroup_driver=mc)
Status in OpenStack Compute (nova):
Expired
Bug description:
Description
===========
Nova services such as:
nova-api-os-compute
nova-conductor
nova-consoleauth
nova-metadata-api
nova-novncproxy
nova-scheduler
> Running on controller nodes (api's) on python3
nova-compute running on python2 on hypervisors hosts (qemu-kvm based)
IF servicegroup_driver=mc (nova.conf):
nova service-list see nova-compute nodes in down state
BUT
IF servicegroup_driver=db it works perfectly fine:
nova service-list see nova-compute nodes in up state
ALSO
IF servicegroup_driver=mc and all nova services running on python2:
nova service-list see nova-compute nodes in up state
Steps to reproduce
==================
1.Run
nova-api-os-compute
nova-conductor
nova-consoleauth
nova-metadata-api
nova-novncproxy
nova-scheduler on python3
Run nova-compute on python2
2. Set servicegroup_driver=mc
3. Execute nova service-list
Expected result
===============
All nova services in actual up state
Actual result
=============
nova-compute in down state
Environment
===========
nova-manage --version
19.3.2
Logs & Configs
==============
nova-compute -> rabbitmq (there is no connection errors, rabbit available
from hosts)

nova-conductor logs:

nova-api:

/var/lib/openstack/lib/python3.6/site-packages/nova/servicegroup/drivers/mc.py:68

So, I'm a little confused, because there is no Rabbit connection
problems (one of possible reason with this behaviour)
I guess problem connected with:
nova-api - memcached - nova-compute
I'll appreciate any help with debug.
