As Ben mentioned, if you are using a fork of OVS, your best bet is to ask in
their forum. However, there

Hi,
I have a question about the data structure of the flow entries saving in
OVS. I install several flow entries in ascending priority, however, when I
want to get these flow entries, I find that the order of the reply seems
randomly. Is the installation of flow entries also randomly in the data

One way to detect Elephant flows on OVS is to enable sFlow on OVS. The
following article
provides an example of Elephant flow detection and marking using OVS / Mininet:

There have been some experiments described using patched
Hey Srinivas,
Right now, ovs has only one dpdk polling thread. We are working on
creating multiple polling threads and pinning polling threads to the same
cpu socket as dpdk interface.
Thanks,

Please ask questions about the dpdk vswitch on its mailing lists.

Dear Arthur,
It was written how to use it in the INSTALL file. Just scroll down a
little bitfar.
List: /make check TESTSUITEFLAGS=--list | grep tunnel /### or you can
"/grep gre/" I haven't checked what will work.
Test case 123 and 477: /make check TESTSUITEFLAGS='123 477'/

tcpdump on the physical interface show GRE packets are segmented to ~9000 if
the VMs vif has MTU 9000. The MTU on the physical NIC is 9192.

Hi,
Can someone tell me how can I use the test suite (tests/*) to test tunnels?
Thanks!

How do one detect Elephant flow on OVS ?. Is there a configurable value, if
so, can you provide more details ?
Thanks

Otherwise it is normal. TSO of virtual driver of VM offload 64k

Hi list,
New to here, and I encountered some seem-to-be-very-basic problems
concerning flow installation. Here it goes:
First, it's about matching normalisation, I tried to install a rule
manually via ovs-ofctl.
sudo ovs-ofctl -O OpenFlow13 add-flow s1
dl_src=00:00:00:00:aa:bb,dl_dst=aa:aa:00:00
Do you mean that GRE offloading is needed for OVS to forward GSO/GRO packets ?
The funny thing is, that it seems to be the VMs MTU that determines what the
GRE MTU will be.
So at VM mtu 1500, packet sizes are:
VM: 64K
VIF: 64K
Bridge: 64K
GRE: 1500 bytes
NIC: 1500 bytes
At VM mtu 9000, packet si
