[dpdk-dev] DPDK on EC2?

[Jeff Wang]

Thanks Andre and Rashmin!

I'm trying to deploy this dpdk-ovs on EC2.

https://github.com/01org/dpdk-ovs

But the way it works on my own machine seems quite different with it does
on the cloud. I'm still confused about the hardware virtualization on EC2.

[dpdk-dev] DPDK on EC2?

[Jeff Wang]

Hi,

I'm trying to deploy DPDK and ovs on an AWS EC2 instance which is running
CentOS 7.

Has anybody had tried to do this? How to bind a NIC to dpdk while it shows
no NICs when I do lspci?

Thanks!

[dpdk-dev] testpmd app issues

[Jeff Wang]

Hi,

I'm new to DPDK.

I have gone through the user guide, set up environment, hugepages. I can
get the helloworld app work. Now, when I tried to play with the testpmd
app, I got the following issue:

[root at localhost dpdk-1.8.0]# build/app/testpmd -c 0x2 -n1 -- -i
--nb-cores=1 --nb-ports=0x1

.

EAL: TSC frequency is ~2594110 KHz
EAL: Master core 1 is ready (tid=e07b3840)

.

It says the core mask is not right. I set it to 0x2 because my CPU
only has 2 cores. I don't quite get it.

Can someone help me with this? And has anyone else encountered the same issue?

Thanks!
