Hi Jamie, Can you run this with --log-level=8 -w 0000:0b:00.0 -w 0000:13:00.0 and post the results here?
(I mean like the following: testpmd -l 1,2,3 -n 1 --log-level=8 -w 0000:0b:00.0 -w 0000:13:00.0 -- --disable-hw-vlan --forward-mode=mac --eth-peer=0,00:00:00:00:33:33 --eth-peer=1,00:00:00:00:44:44 -i --nb-cores=2 --rxq=8 --txq=8 --rxd=8192 --txd=8192) and also to be on the safe side, make sure that in build/.config you have CONFIG_RTE_LIBRTE_VMXNET3_PMD=y (It should be so by default for dpdk-stable-17.11.4) Regards, Rami Rosen On Thu, 6 Sep 2018 at 19:39, Jamie Fargen <[email protected]> wrote: > > Hello- > > Would like to do some performance analysis using testpmd on a RHEL7 VMWare > guest using a VMX3NET network devices.
