-'''UPDATE:''' I've amended the directions to eliminate the need for bridging compatibly. This requires us to not use libvirt and virt-manager/virsh. We want to use open vswitch in it's native mode with out the bridge. This should be a more "flexible" setup.

+    install_vm takes 1 parameter, the name of the disk image to install on (the image created earlier via kvm-img), 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.
