I'm using Open vSwitch to create a switched network between virtualBox guest machines, and i
want that the host OS (Ubuntu 12.04) join this network and to configure it as the gateway of this virtual network:
First, i created a vswitch and i added ports to tap devices (that virtual machines use them as bridged interfaces):
ovs-vsctl add-br sw0
ovs-vsctl add-port sw0 tap0
After that, i set statically the ip of Lubuntu 12.04 virtual machine :
ifconfig eth0 192.168.1.3/24 up
route add -net 0.0.0.0/0 gw 192.168.1.1
In the host os side, i also set the ip address :
ifconfig sw0 192.168.1.1/24 up
At this time, i can ping from Lubunut to Ubunutu. I want
now, in the host machine to use IP masquerade to forward traffic from network 192.168.1.0/24 to my physical interace (connected to Internet) :
sysctl -w net.ipv4.ip_forward=1
iptables -t nat -A POSTROUTING -o eth1 -s 192.168.1.0/24 -j MASQUERADE
So from Lubuntu (the virtual machine), i can ping the Ubuntu eth1 interface, but i cannot reach the real network (e.g: the gateway on real LAN), i have tried :
nslookup google.com
dig @8.8.8.8 yahoo.com
dig @192.168.30.1 google.com

The answer is not really mine, but... Try following Open vSwitch on VirtualBox
There was also a brief text file from some Fedora people on similar subject: libvirt and OpenVSwitch in a form of text file... wasn't able to locate it though.
as per comment, here's short summary:
(1) Create vnet0 interface and br0 bridge:
ovs-vsctl add-br br0
ip tuntap add mode tap vnet0
ip link set vnet0 up
ovs-vsctl add-port br0 vnet0
ip link # (View the created interface)
(2) spin up VM that uses vnet0 interface (as a bridged adapter)
(3) connect bridge br0 to real network:
ovs-vsctl add-br br0
ovs-vsctl add-port br0 eth0
ovs-vsctl add-port br0 vnet0
ifconfig eth0 0 && ifconfig br0 192.168.1.(X) netmask 255.255.255.0
route add default gw 192.168.1.1 br0
route del default gw 192.168.1.1 eth0
