ESXi 5.0 doesn't have SR-IOV sup= port (it's in the code, but is disabled and not usable for customers). VMwa= re introduced SR-IOV support, including out of the box support for Intel Ni= antic 10GbE NICs, in ESXi 5.1.

Subject: Re: [dpdk-dev] rt= e_eth_dev_count() returns 0

As far as I known, DPDK(1.2.3) only= supports the following NICs:
(1) Intel 82576, 82580, I350 chipset based NICs;
(2) Intel 82599, X540T, X520T chipset based NICs;
(3) virtual NICs generated by SR-IOV from (2).

If the NICs on your C220 M3 is one o= f (2), you can run l2fwdvf OR l3fwdvf successfully with SR-IOV enabled in E= SXi.
And I do not know wheather ESXi 5.0 = VMM has SR-IOV function or not.

Further= more, please reference to DPDK release notes.

My Hello app from the DPDK examples runs fine, but I= get the following error when running the l2fwd app:=

=E2=80=9CEAL: Error =E2=80=93 exiting with code: 1

The rte_eth_dev_count() call returns 0, I am using a= CentOS 6.3 Virtual Machine on VMWare esxi 5.0 on a Cisco UCS C220 M3 which= comes with Xeon E5-2600.

I would really appreciate If you could provide some = help to solve this issue.
