Hi,

I am finding an issue on ESXi host running our Linux= VM application.  The DPDK version is 17.11 and VM OS is 3.10.0-1160.8= 1.1.el7.x86_64.

ESXi host version is 7.03.

The NIC is the Intel x710-DA2 in SR-IOV mode.  = Configured on ESXi host 4 virtual functions.

Our VM has one of the four virtual functions from th= e x710 NIC for DPDK port.

 

In our application, when we initialize the port and = all the checks pass, but rte_eth_dev_start() fails for -1 return code.=

The failure from gdb is:

i40evf_configure_vsi_queues(): Failed to execute = command of VIRTCHNL_OP_CONFIG_VSI_QUEUES

i40evf_dev_start(): configure queues failed<= /o:p>

 

Our application requires 1 Rx queue and 4 Tx queues.=

 

When I change the number of Tx queues from 4 to 1 th= e failure is not seen.  However our application requires 4 Tx queues s= o not an option.

This same VM ran successfully when ESXi host was 5.5= .

 

We had our IT department do a sanity check on the ES= Xi host and upgrade any VIBs recommended, but did not resolve the problem.<= o:p>

 

Tried testpmd and also failed for DPDK start.

 

Thanks,

Ed
