[Bug 1747513] Re: OpenVswitch 2.8.0 Stuck on boot when server is Diskless and boot from iSCSI

[James Page]

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.

Title:
  OpenVswitch 2.8.0 Stuck on boot when server is Diskless and boot from
  iSCSI

Status in openvswitch package in Ubuntu:
  Incomplete

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.
