Hi,
Previously, we used ovs 1.4.x and found ovs-vswitchd dropping logs. Then we
upgraded to ovs 1.11.0 as suggested on this mailing list. We did observe
drop of the CPU utilization on host.
However, we still randomly found ovs-vswitchd dropping logs. Some ovs logs
are pasted below.
I have two q
sure, I will try that
Thank you very much

Ah, thanks, Alex
if I want the VMs on host 1 and host 2 to be able to communicate with each
other,
I still need the tunnel?

Well, as the FAQ says,
"""
A physical Ethernet device that is part of an Open vSwitch bridge
should not have an IP address. If one does, then that IP address
will not be fully functional.

The eth1 on br0 still has address "192.168.2.1".

Hi, Alex,
Thank you for the reply,
But my problem is that I can add ports to br0 while keeping connection works, I
cannot make bridge to forward the packet to the correct place
like in the bridge I have 4 ports, eth0 to 192.168.55.1, eth1 to 192.168.2.2
eth3, eth4 are connecting to the hosts

Hi, all
I'm new to openvswitch,
I have two hosts, the setup looks like
host 1: eth0 -> internet , eth1 (192.168.2.1) -> host 2's eth0 (192.168.2.2)
host 2: eth0 (192.168.2.2) -> host1's eth1 (192.168.2.1), eth1 -> internet
I choose KVM as the virtualization platform, and start two VMs in

Hello Gurucharan,
Thank you for your reply.
Yes without the controller, I'm able to ping both nodes on br0.
I'll create the virtual interface on br0. Currently I have set the private ip
on br0 of the VLAN 1751 eth2.1751 interface. I'll move the private ip to the
virtual interface and configur

Hi,
My mail may have been missed out. Resending again..
Can someone please help me with the below use case? Can OvS work with physical
nodes. If yes how do we switch from the virtual to physical interface on
baremetal nodes.
Or connecting the hardware OpenFlow switches to the physical nodes is
I don't think you want "--strict", since you are telling it to delete all flows
with no matches specified at priority 0.

Hello Joe,
I have one question: what is this controller?
Bridge "labBR1"
Controller "tcp:192.168.137.60:6633"
is_connected: true
Is it an Openflow controller?
My guess is that the traffic on you "switch1" generates packet-in
messages and those get sent to the controller which
Hi,
When I send a flow mod message to OVS with a hard timeout and flags set to
request a flow removed message the controller is receiving two messages
when the time passes.
The reason field in the first of these messages is set to

Hello,
I constructed a Flow-mod message with only one 'write action' instruction,
output to controller, and sent it to the OVS. But I got a error message
with 'unsupported instruction'.
Does the OVS support ‘write action’ instruction in Flow-mod Messages?
P.S. I constructed the message according t
23 matches
