Hi
I have a compute node of openstack juno running 2 vms.
Each vm have a nic which is a sriov vf.
In each vm i read packet with dpdk in user space from the sriov vf.
All the 2 vm receive traffic ok.
If in one of the vm i kill the dpdk processes that is listening to the sriov vf , the other vm stop receiving traffic.
Why is one vm/vf influenced by the other?
If i look in the host side with ethtool -S, i can see that all packet are Rx dropped at rx_missed_errors.
Here is the output of lspci
