Using latest RDO Icehouse with RHEL 6.5 (fully updated).

When using OVS VLAN segmentation, after restarting neutron-openvswitch-agent, the logs show

Error: argument "peer" is wrong: "name" too long

The command it's trying to run is

ip link add int-br-eth0.2017 type veth peer name phy-br-eth0.2017

Any suggestions on how to fix this?
