l3fwd fails : Cause: Unable to create the l3fwd LPM table on socket 0

Hello! I am new to DPDK.

When I run "l3fwd" on a Ubuntu 12.04 Virtual Machine, the error is  "Cause: Unable to create the l3fwd LPM table on socket 0". The information about my set-up is as follows:

1) The command that I used to start the VM is:
qemu-system-x86_64 -enable-kvm -m 1024 -localtime -boot d -vga std -name DPDK \
-hda ./ubuntu_desktop_dpdk.img -cpu host \
-net nic,vlan=1,model=virtio,macaddr=00:40:47:1a:0a:44 \
-net tap,vlan=1,ifname=tap-dpdk1,script=no \
-net nic,vlan=2,model=virtio,macaddr=00:40:47:1a:0b:44 \
-net tap,vlan=2,ifname=tap-dpdk2,script=no \
-net nic,vlan=3,model=virtio,macaddr=00:40:47:1a:0c:44 \
-net tap,vlan=3,ifname=tap0,script=no

Host has 4 cores Xeon 4771, but this VM ends up having only one core. Note that I used option "-cpu host" in this qemu command.
On VM, I give control to two ports to the igb_uio. For huge pages, I gave 64x2MB memory to NUMA system using tools/setup.sh script. In another variation, I gave the same amount to non-NUMA system also.

2) The actual command used to start l3fwd and its output (1 core, 1 memory channel, enabled all ports, and ports 0 & 1 both assigned to core 0):

./l3fwd -c 0x1 -n 1 -- -p 0xf --config="(0,0,0),(1,0,0)"

I will appreciate any help. Thanks,
