<p class="MsoNormal" style="margin-bottom:12.0pt">I realised on debugging ovs-dpdk-init script that the main issue is with the following command<br>
<br>
$ screen -dms ovs-vswitchd sudo sg $qemu_group -c "umask 002; ${OVS_INSTALL_DIR}/sbin/ovs-vswitchd --dpdk -vhost_sock_dir $OVS_DB_SOCKET_DIR -c $OVS_CORE_MASK -n $OVS_MEM_CHANNELS --proc-type primary --huge-dir $OVS_HUGEPAGE_MOUNT --socket-mem $OVS_SOCKET_MEM

<p class="MsoNormal" style="margin-bottom:12.0pt">which I guess is starting the ovs-vswitchd application. Before this command, huge pages is mounted and port binding is also done but still the screen command fails.
