Единый интерфейс Devstack не работает в ubuntu 20.04

#openstack #devstack #openstack-neutron

Вопрос:

Пытаюсь вызвать openstack с помощью сценариев devstack с ветвью stable/wallaby (также пытался stable/xena) использовать единый интерфейс со справочной конфигурацией отсюда. Однако при укладке установка завершается неудачно из-за arping . Ниже мой netplan , local.conf и error.log

netplan

However if I enable flat interface and comment out Q_USE_PROVIDERNET_FOR_PUBLIC field as shown in below local.conf though arping works and ovs configuration gets created, however while dowloading the cirros image installation fails. The reason being name resolution fails, able to ping the 8.8.8.8 though curl of google.co.in fails with name or service not found.
