[Jose Phillips]

** Summary changed:

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

** Description changed:

  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 and
- after that i can boot to the server again but when neutron-openvswitch-
- agent reconfigure OVS is unable to restart the server again.
+ 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.
