Hello all,

I've started PoC'ing some ideas around $subject in the topic below and
wanted to ask the wider team for feedback on the approach I'm taking:


My initial idea is to break the job up into the following smaller
multinode jobs that are hopefully easier to understand and maintain.

* nova-multinode-live-migration-py3

A simple LM job using the qcow2 imagebackend and LVM/iSCSI c-vol.

* nova-multinode-live-migration-ceph-py3

A ceph based LM job using rbd for both imagebackend and c-vol.

* nova-multinode-evacuate-py3

A separate evacuation job using qcow2 imagebackend and LVM/iSCSI c-vol.
The existing script *could* then be ported to an Ansible role as part of
the migration to Zuulv3.

Hopefully this is pretty straight forward but I'd appreciate any
feedback on this all the same.
