Hi folks, I have two Intel Xeon servers connected back-to-back using Intel 82599 NICs (a sender to a receiver). I followed the steps in DPDK manual section 9.3 and use single VF direct pass-through to the VM and run testpmd on the VF at the receiver. At the sender side, I run Pktgen and program the VF's MAC address as destination mac and sends them out to the VM at 50% rate.
After booting the VM, according to the manual step 10, I need to take over the physical function by running the testpmd at host side. Then in VM I start the testpmd. The testpmd in VM starts ok without any error, and I also check the "show port info all". However, while I keep sending packets to the VM, the "show port stats all" always reports 0 RX-packet. Actually no packet rx/tx at all. I've check that without running VM, the sender indeed could send packet to the receiver server. I'm wondering how to debug this issue and any comments are very appreciated. btw, one weird thing is that I try to do "set promisc all on", however I check the port info and it is always disabled. Thank you. Regards, William
