But, when I add more VM with DPDK/SR-IOV enabled NIC 1vf 1pf, both VMs reduced the packets reception by 40%. I am not sure where the problem is since with 1 VM packet receive/send is working fine. Here, I would like to debug I/O counters details in ixgbe_vf pmd driver level in DPDK. Can you please through somelight if DPDK has any counters/drop - Statistics collection available or not in ixgbevf I/O level. --
