Hi,
I have observed packet loss  with usvhost dpdk interfaces even at a very
small rate  .
This is because virtqueue [dev->virtqueue]  is found to be full,
and my application should drop the packets .

some one pls help me ,
how can I avoid this loss .

--------
thanks
srinivas.

Maybe your virtio guest is slow in processing the packets.
Could you refer to the retry mechanism in the vhost example?  search
enable_retry in switch_worker in examples/vhost/main.c.
