Bug Description

When upgrade openvswitch from 2.5 to 2.8 based on "Xenial-Pike" Repository of openstack the computer got stuck on boot .

the way to recover back is booting on safe mode deleting conf.db

the workaround that i found is change the systemd file openvswitch-nonetwork.service

from:
After=apparmor.service local-fs.target systemd-tmpfiles-setup.service
Wants=network-pre.target openvswitch-switch.service
Before=network-pre.target openvswitch-switch.service

to
PartOf=openvswitch-switch.service
Wants=openvswitch-switch.service

looks like starting openvswitch is killing all network connectivity.

summary: - OpenVswitch 2.8.0 Stuck on boot
+ OpenVswitch 2.8.0 Stuck on boot when server is Diskless and boot from
+ iSCSI

the -nonetwork unit starts early as its possible that system boot may depend on network interfaces that will be configured as part of openvswitch.

It would be helpful to understand the ovs configuration that you have to flush from the OVS DB to workaround this problem.
