Vboxnet2 - are virtual networks setup up by virtual box with
your host machine. This is the way your host can communicate with the virtual machines. These
networks are in turn used by virtual box VM’s for OpenStack networks, so that OpenStack’s
services can communicate with each other.Network NodeStart your Controller Node the one you setup in previous section.Preparing Ubuntu 12.04After you install Ubuntu Server, go in sudo mode$sudo suAdd Havana repositories:#apt-get install ubuntu-cloud-keyring python-software-properties software-properties-common python-keyring#echo deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/havana main >> /etc/apt/sources.list.d/havana.listUpdate your system:#apt-get update#apt-get upgrade#apt-get dist-upgradeInstall NTP and other services:#apt-get install ntp vlan bridge-utilsConfigure NTP Server to Controller Node:#sed -i 's/server 0.ubuntu.pool.ntp.org/#server0.ubuntu.pool.ntp.org/g' /etc/ntp.conf#sed -i 's/server 1.ubuntu.pool.ntp.org/#server1.ubuntu.pool.ntp.org/g' /etc/ntp.conf#sed -i 's/server 2.ubuntu.pool.ntp.org/#server2.ubuntu.pool.ntp.org/g' /etc/ntp.conf#sed -i 's/server 3.ubuntu.pool.ntp.org/#server3.ubuntu.pool.ntp.org/g' /etc/ntp.confEnable IP Forwarding by adding the following to /etc/sysctl.conf:net.ipv4.ip_forward=1
