Bug description:
[Impact]
Fixes nova to not fail when scheduling a vm that previously belonged to a server group that has been deleted.
[Test Plan]
* deploy Openstack Yoga with shared storage e.g. Ceph
* create a server group (e.g. affinity) and boot one or more instances within that group:
openstack server group create --policy affinity sg1
openstack server create --image jammy --flavor m1.small --key-name testkey --nic net-id=private vm1 --hint group=e29105e1-06a2-40fa-85fa-899db944a82 --wait
* delete the server group:
openstack server group delete sg1
* poweroff the compute host where the vms are running
* evacuate the vms from the powered down host:
nova evacuate vm1 juju-882778-lp1890244-focal-yoga-13.cloud.sts
* check vms are ACTIVE and reachable on new compute host(s)
[Regression Potential]
No regressions are expected as a result of this fix.
-------------------------------------------------------------------------
Description
===========
We created a server group and started some instances in it.
Later we removed the server group.
Some time later, we had to evacuate these instances, but this failed, because the
scheduler removed all available hosts during filtering.
Steps to reproduce
==================
* create a server group
* start some instances in this group
* delete the server group
* ( hard poweroff your hypervisor )
* evacuate the instances
Expected result
===============
The instances are evacuated
Actual result
=============
The instances run into ERROR-state, because the server group is not found.
Environment
===========
* Kolla deployed OpenStack Train
* Ubuntu 18.04 / KVM + Libvirt
Logs & Configs
==============
scheduler tells:
