Hello,
Using Floodlight to connect to OVS 1.4 on 17 different hosts - after reboot
the OVS fail-mode has to be cycled from secure to standalone before
connecting to the Controller. Is this intended or a bug?
Thanks,

Hello,
This may be purely speculative, or isolated to say the least, but has
anyone experienced an issue where they have to cycle fail modes to get
controller connectivity when first connecting to an Openflow controller?

Hello,
What is the difference between adding a physical interface (eth0,
eth1etc) to a bridge and not adding it to the bridge. After reading the
FAQ I understand how to add a physical port to a bridge and why its best
not to give it an IP but I don't understand what the difference would be if

How do you compensate for a setup where OVS is connected to an OpenFlow

deletion when tunneling is not in use but OVS makes one heck of an
encapsulator when paired with JSON RPC and OpenFlow.

Hello,
Our research meeting today ended on the question of whether or not it would
be possible or system breaking to tunnel to a large number of hosts using
OVS. So I threw my JSON RPC tunnel creator into a loop and around 234 on
bridge0 decided to stop. That being said I noticed with the ovs-vsct

Forgive me as I am a student and not a Linux guru At present,
installing OVS from apt-get will yield version 1.04. Is there anyway to get

Hello,
Is it possible to get OVS to GRE encapsulate ALL traffic leaving a host
regardless of the packet's destination? We're trying to find a way to make
OVS encapsulate every packet that leaves a host inside of a GRE header and

Thanks Always,

Hello Cali,
Have you tried using tunctl to create the tunnel adapter and then adding
that adapter to the bridge the gre port is assigned to? That being said,
what are you using the tun adapter for - is it tun/tap to tap VM's into the
bridge?
