Greetings,
We're about to use OVN in a large production environment :-)
Well, not really "production" production, but having fun testing
it, looking if we can use it in such way. While functionality is
good for us, two question appear - scalability and availability.

Is it safe to use in-kernel openvswitch module? I was always
sceptical about it, because OVS's datapath module always was more
up to date. On the other hand, latest OVS (2.3.1) doesn't work
with 3.18 kernel, which we are trying to use.
So, how stable is combination of OVS 2.3.1, kernel 3.18 and

Hi,
When saving/restoring bridge state during force-reload-kmod
dynamic and 'scope link' addresses are not restored. This breaks
IPv6 in a very bad way, because restored interface no longer have
link-local (fe80::) address. Because of that it is unable to
receive RAs and assign global dynamic ad

Hi,
While openvswitch does not support InfiniBand natively, it is
still possible to use IB features. One can create GRE tunnels
with endpoints on IPoverIB interface.
Recently I've come to an idea to use RDMA for tunneling packets
between hypervisors.
Since all tunnels are point to point, one ca

You can turn this error into warning by adding

I can see "ovs" Python module in openvswitch sources, but can't

Hi.
This is something, that I would like to share with community.
Attached file is a nosource rpm for RHEL (tested on RHEL 5.5 and
RHEL 6). Inside you will find SysV initscript, logrotate config,
modules autoload script, configuration file and ifup/ifdown
scripts for network-scripts subsystem.

From ovs-dpctl(8):
A single machine may host up to 256 datapaths (numbered 0 to
