Selecting Linux distribution for DPDK applications: CentOS or Debian

Selecting Linux distribution for DPDK applications: CentOS or Debian

[Daniel Kan]

I’m deciding between Debian 7.3 (3.2.0 kernel) and CentOS 6.5 (2.6.32 kernel) for production. I’m wondering if anyone has recommendation. We run the DPDK application in a virtualized environment. Currently, we configure NICs in pass-through mode which gives the best performance. In the future, we plan to use DPDK with paravirtualized nics (eg. vmxnet3-usermap). Thanks.

Hi Dan,

Intel DPDK release notes(1.5.2) mention the following tested OS --
* Fedora release 18
* Ubuntu* 12.04 LTS
* Wind River* Linux* 5
* Red Hat* Enterprise Linux 6.3
* SUSE Enterprise Linux* 11 SP2

I have personally used Fedora 18 and it works fine for me for virtualization including SRIOV and pass through as well as virtio with KNI backend.
So I am tending to stick to Fedora 18.

I don't know why is CentOS not tested and mentioned in release notes.

Regards
-Prashant

We're using CentOS 6.5 and Ubuntu 12.04 and don't see any issue with both
of them.

Hi Dan,

We are also using Debian 7.3, from the DPDK v1.3.1 up to version 1.5.1r1.
it works completely fine.

Re: Selecting Linux distribution for DPDK applications: CentOS or Debian

Thanks for the all the feedbacks. Ubuntu 12.04 LTS has 3.8.x kernel and Fedcore 18 has 3.10.x kernel. Both kernels are not compatible with the vmxnet-usermap driver which supports only up to 3.2.x. virtio-net-pmd requires kernel 3.8.x and qemu 1.5 for multi-queue support. Since CentOS’s kernel is on its own path, I’m wondering if anyone has any issue with virtio-net-pmd on CentOS 6.x. 

Prashant, CentOS is essentially the same as RHEL 6.3 minus the support.

Hi Daniel,

virtio-net-pmd (dpdk-1.5) works on CentOS 6.x . Just verified basic packet
flow with one queue.

Thanks,
Selvaganapathy.C.
