Ubuntu 13.10: install / use openvswitch within KVM

Here are trial and error logs when installing openvswitch.

During the following operation, you will lose internet connectivity.

# tail -1 /etc/lsb-release ;uname -ri DISTRIB_DESCRIPTION="Ubuntu 13.10" 3.11.0-15-generic x86_64

install openvswitch via apt-get

# apt-get install openvswitch-switch

/etc/network/interfaces

:# cat /etc/network/interfaces # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback auto eth0 #iface eth0 inet manual iface eth0 inet dhcp

reboot the OS.

after booting the OS, you can not access to the internet.

type the following command.

2001  ovs-vsctl add-br br0 2003  ovs-vsctl add-port br0 eth0 2004  ifconfig eth0 0.0.0.0 2006  ifconfig br0 192.168.11.100 2010  route add default gw 192.168.11.1

I can not figure out how to write the last three commands(ifconfig eth0, ifconfig br0, route add..)  in /etc/network/interfaces files correctly..

So I type “ifconfig eth0, ifconfig br0, route add ..” commands every time when booting the OS…

In my environments, when booting the OS, eth0 gets an IP from DHCP, and then I login to the OS and type “ifconfig eth0 0.0.0.0, ifconfig br0 …, route add..“ via shell prompt.

[ use KVM with openvswith ]

edit VM config

virsh edit <vm name>

<interface type='bridge'>      <mac address='mac address'/>      <source bridge='br0'/>      <virtualport type='openvswitch'>
