I have installed a 3 node Openstack cluster. (1 Controller + network and 2 compute node). Installation using packstack happened successfully. After rebooting the controller + network server node the neutron-openvswitch-agent went into failed state.

What OS are you running on ? Is OVS version 2.1.3 ?

UPDATE as of 04/21/2015

For now downloaded openvswitch-2.3.1-2.el7.src.rpm from
installed and did a local build , afterwards upgraded  OVS to 2.3.1

#yum install openvswitch-2.3.1-2.el7.centos.x86_64.rpm \
openvswitch-debuginfo-2.3.1-2.el7.centos.x86_64.rpm \
openvswitch-devel-2.3.1-2.el7.centos.x86_64.rpm \
openvswitch-test-2.3.1-2.el7.centos.noarch.rpm \

Rebooted nodes.

Controller && Network Node in Cluster ( normal behaviour after upgrade)
