Title:
Neutron failed to spawn rootwrap process.
Status in neutron:
Expired
Bug description:
I installed Openstack Liberty for multi-node deployment, during the
installation of the the neutron-openvswitch-agent on compute node,
the neutron-oenvswitch-agent failed to start.
Checking the log from /var/log/neutron/openvswitch-agent.log, it looks
like neutron failed to spawn rootwrap process.
The details log as followings,
