Hello I observed an issue with OVS 2.3.2 on CentOS 6.6 KVM , kernel 2.6.32-504.el6, with 25 tenant VMs where it stopped responding to ARPs all of a sudden. There are 2 OVS bonds in balance-tcp mode in this configuration. OVS service was restarted to resolve this state . Below logs were

[ovs-discuss] Strange flows in bridge/dump-flows

When I connect my (ryu) controller to OvS (with DPDK) while all data-ports are down, I always see the strange flows in bridge/dump-flows below. Then when b8:af:67:84:90:d7 tries to send an arp packet, OvS floods it. Could someone please explain why (or who) adds these flows into OvS? Thanks in

[ovs-discuss] combining Geneve and VXLAN tunnels

Hi, I have a setup with three machines with an OVS switch each. 1 and 2 are connected via VXLAN tunnel, 2 and 3 are connected via Geneve tunnel. The OVSs have each an IP address assigned. ping from 1 to 2 works and ping from 2 to 3 works. But trying to ping from 1 to 3 or 3 to 1 does not work,
