Hello all. I'm trying to get OVS working with Intel 82599 and SR-IOV.
Basically what I currently have is an Ubuntu 12.04 with custom kernel (3.14.23) and Intel 82599 NIC (eth0) and OVS 1.10 installed. There is also openvswitch-datapath-dkms 2.3.0 which was built for 3.14.23. There is a br-eth0 bridge in OVS, which is connected to eth0 interface. Bridge br-mgmt is connected to br-eth0 and is using VLAN tag 102. Network connectivity via br-mgmt -> br-eth0 -> eth0 chain work fine as long as 82599 Virtual Functions (VFs) are disabled. Once I enable at least 1 VF (echo 1 > /sys/bus/pci/devices/0000:04:00.0/sriov_numvfs), server looses connectivity via this chain. If I try to set up VLAN 102 via ip link directly on eth0, it works. With the help of tcpdump I've found out that packets don't go any further than br-eth0. Software versions: Ubuntu 12.04 with custom kernel 3.14.23 openvswitch-switch 1.10.1+git20130823-0ubuntu3~cloud0 openvswitch-datapath-dkms 2.3.0 On Ubuntu 12.04 with 3.11.8-generic, same openvswitch-switch and openvswitch-datapath-dkms-lts-saucy there is no such issue. Any suggestions? Thanks. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
