Title:
Packets dropped in br-int bridge
Status in neutron:
Expired
Bug description:
Hello,
We have two VMs that communicate with each other. Like VM-A and VM-B,
on different hosts, host-A and host-B.
Now, we encountered one problem:
VM-A sends one burst packets like 300K packets(each packet is less than 100
bytes) per seconds to VM-B. But VM-B could only receive about 100K packets. The
burst last about 2 seconds.
We did tracing where the packet got dropped. And found on host-B, the virtual
port "patch-tun" in br-int could receive all packets.
But the "qvoxxx" interface on br-int couldn't receive all packets.
We tried to dump: ovs-appctl bridge/dump-flows br-int and ovs-ofctl
dump-ports br-int.
But no significant drop counter could match such number of the packets drop.
Need your expertise to check where could the packets got lost. Any
configuartion could impact on such situation?
Thanks,
Mark
