     install_vm takes 2 parameters, the name of the disk image to install on (the image created earlier via kvm-img) and the iso to mount. It takes the default vnc port :0 (tcp port 5900), and also mounts a cdrom. The vnc port number is also the last digit of the mac address. start_vm has two arguments, the first is also the image name, the second is which vnc port to take (1-9). It also follows the last digit mac convention.

+=== Incase you are using regular linux bridgeing ===
+
+In winlab we used simple bridgeing instead of the open-V-switch. Many steps remain the same however there are a few adjustments. These adjustments basically have to do with installed packages and the ifup and ifdown scripts. 
+
+ 1. The package installed was
+    {{{
+    apt-get install bridge-utils
+    }}}
+ 1. /etc/networks/interfaces was reconfigured to reflect the bridged interface:
+    {{{
+# This file describes the network interfaces available on your system
+# # and how to activate them. For more information, see interfaces(5).
+
+# The loopback network interface
+auto lo
+iface lo inet loopback
+
+# The primary network interface
+auto eth0 
+iface eth0 inet dhcp
+
+auto  eth1
+iface eth1 inet manual
+
+auto br0
+iface br0 inet static
+address 192.168.200.67
+        network 192.168.200.0
+        netmask 255.255.252.0
+        bridge_ports eth1
+        bridge_stp off
+        bridge_fd 0
+        bridge_maxwait 0
+    }}}
+ 1. The ifup and ifdown scripts were replaced with the brctl equivalents:
+    {{{
+/etc/ifup-br0
+--------------------------------------------------------------------
+#!/bin/sh
+
+switch='br0'
+/sbin/ifconfig $1 0.0.0.0 up
+/sbin/brctl addif ${switch} $1
+--------------------------------------------------------------------
+
+/etc/ifdown-br0
+--------------------------------------------------------------------
+#!/bin/sh
+
+switch='br0'
+/sbin/ifconfig $1 0.0.0.0 down
+/sbin/brctl delif ${switch} $1
+--------------------------------------------------------------------
+   }}}
+1. The kvm startup script was modified to use these scripts instead of their ovs coutnerparts:
+   {{{
+vmhost2:/root# more start_vm 
+kvm -daemonize -vnc :$2 -m 2048 -smp 2 -net nic,model=virtio,macaddr=00:11:22:EE:EE:E$2 -net tap,script=/etc/ifup-br0,downscript=/etc/ifdown-br0 -drive file=$1
+   }}}
+   Where $1 is the image name, and $2 is the last digit of the mac and it's matching vnc port number.
