[dpdk-users] Fail to build Memnic in Ubuntu 14.04

[dpdk-users] Fail to build Memnic in Ubuntu 14.04

[Royce Niu]

Hi

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!

Hello,

The memnic code is not updated since 2014-09-30. I am not sure if it got 
replaced by something else in OVS or just fell asleep.

But I think that is why you are getting so insanely many errors, it fell 
too far behind DPDK to work.

If you can find an old DPDK released around this time listed here it 
might help narrow down if that might be the root cause:

http://dpdk.org/browse/memnic/log/

However a DPDK that old will probably fail to build due to kernel 
version issues.

Dear Matthew,

I think my DPDK works. However, I believe SR-IOV is faster than VirtIO in
VM, so I want to have a try.

Is there any other solution to achieve SR-IOV with DPDK. I am amazing that
MEMNIC is stuck at 2014. Nobody needs that with DPDK in VM?
