Run on SR-IOV NIC

[anuradhapriyankara]

Hi,
I'm trying to run warp17 v1.6 on a virtual machine which has 2 virtual NICs of Intel X710 virtualized using SR-IOV.
When I'm trying to run test_3_http_multiple.cfg the following error occurs,

PMD: i40evf_dev_configure(): VF can't disable HW CRC Strip USER1: WARNING: Virtual driver does not support multiple rings, use single packet core!! USER1: ERROR: Failed rte_eth_dev_configure(0, 1, 1, ..,), returned Invalid argument(22)! EAL: Error - exiting with code: 1 Cause: ERROR: Failed initializing the Ethernets ports!

I have tried to run with qmap-default and manual qmap using following commands,

sudo ./build/warp17 -c F -n 1 -m 8000 -- --qmap 0.8 --qmap 1.4 --tcb-pool-sz 1200 --cmd-file ./examples/test_3_http_multiple.cfg --ucb-pool-sz 0 --tcb-pool-sz 1200

sudo ./build/warp17 -c F -n 1 -m 8000 -- --qmap-default max-q --tcb-pool-sz 1200 --cmd-file ./examples/test_3_http_multiple.cfg --ucb-pool-sz 0 --tcb-pool-sz 1200

I'm sure the error has something to do with virtualization because when I directly mounted my X710 to VM, the above commands worked. Since it recommends to use single packet core I have used qmap just like above to assign only one core to each port. Am I doing it wrong or doesn't warp17 supports SR-IOV? I couldn't find that anyone used SR-IOV with warp17 so far. Since DPDK supports SR-IOV virtual devices, I assume warp17 should have no problem. Here is the complete warp17 log in case you need it,
