Hi
I am try to learn about openflow and openvswitch. The setup which I am trying to create

Controller
/\
/ \
/ \
/ \
Ovs Br1———–Ovs Br2
| |
| |
VM1 VM2

The setup is on single Ubuntu host machine. The OVS Br1 and Br2 is connected using patch cable and VM1(Qemu-kvm) and VM2(Qemu-kvm) are connected to respective Bridges using tap interface created using tunctl. VM1 and VM2 are different subnet. I want ping from VM1 to VM2. How should I do it using openflow controllers.

Thanks in Advance
Deepankar

Ubuntu 12.10 runs kernel 3.5. According to http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob_plain;f=FAQ;hb=HEAD that kernel version is only supported by Open vSwitch 1.9.x, which isn’t out yet. Right now the latest is Open vSwitch 1.7.1, so your best bet is Ubuntu 12.04, which has kernel version 3.2

Brad, I’ve had similar experiences with Ubuntu Server 12.10, and have not yet been able to find a workaround. As soon as I figure out how to make it work, I’ll post more information here.

So I tried this on Ubuntu Server 12.10 … and I crashed and burned big time. The brcompat module wouldn’t load to save my life.

But it worked like a charm on 12.04.

Thanks Scott!

To clarify, here is my interfaces file looks like:

# eth1 is to physical interface that attached to br0
auto eth1
iface eth1 inet static # static, not manual
address 0.0.0.0

auto br0
iface br0 inet static
address x.x.x.x
netmask x.x.x.x
gateway x.x.x.x

Scott, to bring eth0 up automatically on boot, I added “address 0.0.0.0″ below the “iface eth0″ line.
