It seems you're using 1.11. Could you try with 2.1.x? fbl On Wed, Jul 23, 2014 at 01:20:43PM -0700, Tom Samburg wrote: > We are running in to some interesting conditions with openvswitch in our > environment.  We are running OVS on KVM (on RHEL 6.5).  We have an interface > (“production traffi

Here's some code from my project that does it. Unfortunately it's quite complicated. some helper methods: protected FlowBuilder base() { return new FlowBuilder() .setTableId(getTableId()) .setBarrier(false) .setHardTimeout(0) .setIdleTim

I has missed this earlier because the timestamps on OVS logs are not matching the system time. Here is the logs from OVS. The last few lines about non existent port 65534 and the netlink errors may be the relevant ones I hope: 2014-07-22T05:08:54.085Z|1|vlog|INFO|opened log file /var/log/open

[ovs-discuss] ovsdb-server process high cpu

We are running in to some interesting conditions with openvswitch in our environment.  We are running OVS on KVM (on RHEL 6.5).  We have an interface (“production traffic”) attached to OVS and our vm that is our router is connected to the vswitch.  Everything with that is working perfectly.  We

Re: [ovs-discuss] Hello version 0

Ben, It was more about sanity tests on OVS than anything else (and hardware switches using OVS as its stack). Naturally, if a controller is trying to negotiate version 0x00, there is something wrong with the controller, no question about it. The issue is not that. The issue was more about how OVS

Thank you all for your reply. Hope that I can find something :) @Christopher: I think TABLE in this page mentions to a logical port, not the table in "table group". On 23 July 2014 19:07, Rob Adams wrote: > Here's some code from my project that does it. Unfortunately it's quite > complicated.

[ovs-discuss] OVS MPLS label switching across multiple vendors

Hello Ben and others, I have a physical hybrid testbed network with OVS switches (i.e. Pica8 hardware switches) as MPLS label edge routers and Juniper MPLS switches as core MPLS label switching routers. I want the edge OVS switches to push MPLS labels on to the incoming flow traffic and the core
