Hi chen,
What Jesse is pointing out is that your problem seems unrelated to OVS. In
particular, the low throughput you observe is probably related to somet

Hi list,
We're working under Openvswitch + Openstack, the kernel is
2.6.32-358.114.1.openstack.el6.x86_64, and OVS is openvswitch.x86_64
1.10.0-1.el6.
We tested the bandwidth between the virtual machine (host 1) and a physical
machine (host 2). (The link between host 1 and host 2 is 10 G

Some NICs lose other forms of offloading
Ok,
At this time, i suppress vlan acceleration feature from igb driver in
kernel,
