As requested from the #openstack-meeting for Nova, I'm posting my nova-spec exception proposal to the ML. Spec: https://review.openstack.org/#/c/103797/3/specs/juno/virtio-scsi-settings.rst Code: https://review.openstack.org/#/c/107650/ - Nikola Dipanov was kind to be the first core sponsor. [1] - This is an optional feature, which should make it a low risk for Nova. - The spec was posted before the spec freeze deadline. - Code change is reasonable and available now. Thank you!
