Hello, All: I've just installed OVS on my Xen host and I'm wondering if there's a recommended configuration for bonding [pysical] interfaces with OVS? e.g., My host system has six [physical] interfaces. I've combined those [physical] interfaces to create three bonded interfaces: 'bond0', 'bond1', and 'bond2'.
For the initial OVS implementation, I created three virtual bridges: 'EXT', 'MGT', and 'SAN': > [root@xen-2 ~]# ovs-vsctl show > 0dfeba4c-bcae-4773-8bd9-582a9ebbd01a > Bridge SAN > Port SAN > Interface SAN > type: internal > Bridge EXT > Port EXT > Interface EXT > type: internal > Bridge MGT > Port MGT > Interface MGT > type: internal > ovs_version: "2.3.2" Then I removed the IP address from the bonded interface 'bond2' (manually *and* via configuration files) and connected it to the virtual bridge 'EXT': > [root@xen-2 ~]# ovs-vsctl show > 0dfeba4c-bcae-4773-8bd9-582a9ebbd01a > Bridge SAN > Port SAN > Interface SAN > type: internal > Bridge EXT > Port "bond2" > Interface "bond2" > Port EXT > Interface EXT > type: internal > Bridge MGT > Port MGT > Interface MGT > type: internal > ovs_version: "2.3.2" This works well enough but, after a reboot, the 'bond2' interface refuses to pass any traffic to the [physical] gateway, XXX.YYY.237.1 until I disconnect the bond (i.e., 'bond2') from the virtual switch and re-attach it: > [root@xen-2 ~]# ping -c3 XXX.YYY.237.1 > PING XXX.YYY.237.1 (XXX.YYY.237.1) 56(84) bytes of data. > From XXX.YYY.237.65 icmp_seq=1 Destination Host Unreachable > From XXX.YYY.237.65 icmp_seq=2 Destination Host Unreachable > From XXX.YYY.237.65 icmp_seq=3 Destination Host Unreachable > > --- XXX.YYY.237.1 ping statistics --- > 3 packets transmitted, 0 received, +3 errors, 100% packet loss, time 2937ms > pipe 3 > > [root@xen-2 ~]# ovs-vsctl del-port EXT bond2 && ovs-vsctl --may-exist > add-port EXT bond2 > > [root@xen-2 ~]# ping -c3 XXX.YYY.237.1 > PING XXX.YYY.237.1 (XXX.YYY.237.1) 56(84) bytes of data. > 64 bytes from XXX.YYY.237.1: icmp_seq=1 ttl=64 time=56.7 ms > 64 bytes from XXX.YYY.237.1: icmp_seq=2 ttl=64 time=48.8 ms > 64 bytes from XXX.YYY.237.1: icmp_seq=3 ttl=64 time=47.6 ms > > --- XXX.YYY.237.1 ping statistics --- > 3 packets transmitted, 3 received, 0% packet loss, time 2049ms > rtt min/avg/max/mdev = 47.650/51.073/56.724/4.033 ms Should I destroy the 'bond2' interface and create the bond using OVS instead? Or is this configuration correct?
