Dear all,

I want to install an OVS/memnic software in a KVM virtual machine.

For the higher speed, I install memnic/pmd (SR-IOV) instead of virtio,
since I believe SR-IOV is faster than virtio.

But, I meet some trouble when I build the memnic following the doc (
http://dpdk.org/doc/memnic-pmd)

I download the most updated software DPDK 2.2.0 and memnic 1.3.

My system is :
1. 2 VCPU 2G Mem
2. Ubuntu 14.04 64bit
3. updated packages


I build DPDK successfully, but when I build memnic in VM according to the
doc.
 A lot of error message displays:

------------------------------------------------------------------------------------------------------------------


Then, I tried DPDK 2.0 and 1.8.
with both of these version, I still meet a lot of errors just like 2.2

So, I want to ask

1. How to solve the problems?
2. Can I install OVS with SR-IOV feature by other ways?

Thanks!
