Hi Martins,
This is correct. This is due to xenserver's python 2.4 where requires

for setting up all flows on the switch. Thus, if the

Also, if you use OpenFlow then instead of using ovs-ofctl you can query OVS

Hi Sonny,
The wireshark dissector only decodes streams as OpenFlow if they are
running on tcp port 6633. In order to get it to decode non 6633 streams you
can right click on the stream->decode as->and set it to decode as OFP.

Either way the only action you should need is output I think (You

Example:
OFPT_PACKET_OUT (xid=0x0): in_port=LOCAL actions_len=16

This packet is output to ports 1 and LOCAL,but should just output to port 1.

I'm using the kernel version not the userspace ( unless my understanding of

Hello,
I'm wondering how much of userspace ovs can be run not being root. I've done
the following:
mkdir -p ~/etc/openvswitch
ovsdb-tool create ~/etc/openvswitch/conf.db vswitchd/vswitch.ovsschema
ovsdb-server ~/etc/openvswitch/conf.db \
--remote=punix:~/usr/local/var/run
Hello I'm trying to use openvswitch in userspace. I'm following the
instructions here:
http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob_plain;f=INSTALL.userspace;hb=HEAD
Though when I run I get:
[root@chimney arosen]# ovs-vsctl add-br br0
Mar 29 20:36:14|2|stream_unix|ERR|/
This may be a silly question but if a dp does not have an IP address then
you have to use out-of band right?
