[Rdo-list] Heads up: openstack-neutron-agent fails to start w/o python-psutil

[Kashyap Chamarthy]

Heya,

I just upgraded my Fedora 20 Havana setup to IceHouse, and, restarting
openstack-neutron-agent fails with the below:

=================================
  $ systemctl start neutron-openvswitch-agent
  $ systemctl status neutron-openvswitch-agent

Workaround for now - explicitly install python-psutil:

  $ yum install python-psutil.x86_64

  $ systemctl start neutron-openvswitch-agent

  $ systemctl status neutron-openvswitch-agent -l

Not sure if others are encountering this too?
