[Lxc-users] 10GbE Interface

[Mayur Gowda]

Hello All,

As planned I got 10GbE interfaces(with linux TOE) on my server(long
wait...!!) and got two debian containers up with following configuration:

>Set macvlan on the 10GbE physical interface
      * sudo ip link add link eth0 address 00:00:00:ab:00:01 macvlan0 type
macvlan mode bridge*

> Setup containers with macvlan

   * lxc.network.type = macvlan
    lxc.network.macvlan.mode = bridge
    lxc.network.link = eth0*

The containers can ping eachother but the problem is they are no way
near the 10gig mark (throughput IPERF < 1Mbps). Am I missing any
configuration here? my goal is to bridge the containers @ 10gig using
macvlan. The veth bridging yields 2.8Gbps ,with MTU tweak, but thats
the maximum I can get to. Need your expertise on pushing the rates !


Thanks & Regards

Mayur
