Re: [ovs-discuss] How to reset counters of ovs-flows ?

If you can do without the flows momentarily, you could delete all the flows and then replace them. On Wed, Mar 29, 2017 at 10:28:13AM +0530, f 62 wrote: > Getting this error with OpenFlow1.0 > > sudo ovs-ofctl -O OpenFlow10 --readd replace-flows br-int /tmp/br_int > > ovs-ofctl: switch does not

Getting this error with OpenFlow1.0 sudo ovs-ofctl -O OpenFlow10 --readd replace-flows br-int /tmp/br_int ovs-ofctl: switch does not support any of the usable flow formats (OXM,NXM+table_id) Is there any other way to achieve same ? On Tue, Mar 28, 2017 at 10:17 PM, Ben Pfaff

Hello, I meant VM1 - VM2(ovs) - VM3.. Yes, the host is Linux. The VMs are already connected without the OVS I want to create a topology such that communication goes via OVS in VM3. On Mar 29, 2017 01:03, "Yi Tseng" wrote: Hi You mean: VM1 -- VM2(with ovs) -- VM3 ?

Re: [ovs-discuss] Error attaching device to DPDK

Once again thanks to Brad for helping me resolve this issue. One other thing that I could suggest is that to throw a WARN message in the logs if more than 1 CPU is found and memory is not set for all CPUs especially when using DPDK. My read on the situation was that memory was going to be

Re: [ovs-discuss] Error attaching device to DPDK

Hi folks, I have been helping Shivaram off-list with this problem and just wanted to update this thread with the solution. Basically the issue was with how hugepages were being preallocated by OVS for use with DPDK. I believe by default OVS sets other_config:dpdk-socket-mem to "1024,0". Which

Hi You mean: VM1 -- VM2(with ovs) -- VM3 ? or VM1 -- ovs -- VM2 -- ovs -- VM3 I assume that your host system is Linux You can create veth pairs. And attach veth interfaces to VMs and ovs. -Yi 2017-03-28 14:21 GMT-07:00 Justin Pettit : > > > On Mar 28, 2017, at 3:48 AM,
