box with your host machine. This is the way your host can
communicate with the virtual machines. These networks are in turn
used by VirtualBox virtual machines for OpenStack networks, so
that OpenStack’s services can communicate with each other.When you reboot the controller node on the VirtualBox
virtual machine, you might lose Internet and network
connectivity. Restart the networking service and use the
ping command to check whether the network
interfaces can communicate over the given networks.To avoid issues on the VirtualBox virtual machine
(controller node), save the virtual
machine state instead of completing a reboot or
shut down.It is advised to take regular snapshots of the Virtual Box
Virtual Machines (controller node) after each section. This will
help you to save your session and revert back to it in case you
break something while deploying OpenStack.controller nodeStart your controller node the one you setup in previous
section.Preparing Ubuntu

/etc/network/interfaces fileOpen /etc/network/interfaces and edit
file as mentioned:# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# This file is configured for OpenStack Control Node by dguitarbite.
# Note: Selection of the IP addresses is important, changing them may break some of OpenStack Related services,
# As these IP addresses are essential for communication between them.

discovering, registering, and retrieving virtual machine images.
Glance has a RESTful API that allows querying of VM image metadata
as well as retrieval of the actual image.VM images made available through Glance can be stored in a
variety of locations from simple file systems to object-storage
systems like the OpenStack Swift project.Glance, as with all OpenStack projects, is written with the
following design guidelines in mind:Component based architecture: Quickly adds new
behaviorsHighly available: Scales to very serious workloadsFault tolerant: Isolated processes avoid cascading
failuresRecoverable: Failures should be easy to diagnose, debug,
and rectifyOpen standards: Be a reference implementation for a
community-driven apiInstall Glance:#apt-get install -y glanceUpdate
