Comment 10 for bug 1902002

this fails on ovs jobs too by the way even with https://github.com/openstack/devstack/commit/47f76acbbac350ea18df6a9463876d38c3a13539 applied as can be seen in

https://zuul.opendev.org/t/openstack/build/bd65ccd7f7724156a53ddbab3e267b13
in that case the openstacksdk-functional-devstack job which uses ovs faild on limestone because the node did not have an ipv4 address at all.
