This document outlines the process of implementing OpenStack on 4 machines each with Intel Core processors, 8GB RAM and Ubuntu 14.04. It discusses OpenStack components like Nova, Glance, Swift etc. Devstack was used to deploy OpenStack which pulls code from git repositories. Procedures included installing components without clustering, LVM, MAAS and Trove. Issues faced included TFTP booting, Wake on LAN, image importing and accessing instances. In conclusion, the team was able to understand OpenStack functionality which was the goal of the project.

3. Machine Configuration
Machine ID pc1
Processor Intel Core i5-3470T CPU @ 2.90GHz x 4
Operating System Ubuntu 14.04 LTS
Operating System Type 64-bit
Disk Size 500 GB
Memory 8 GB
CD / DVD Drive Yes
IP Address Dynamic Allocation
Number of Machines 4

4. Introduction to Cloud Computing
 Built on existing technologies such as virtualization and
clustering
 A common resource pool
 Efficient use of hardware
 Three basic service models:
 SaaS, software as a service
 PaaS, platform as a service
 IaaS, infrastructure as a service

5. Introduction to OpenStack
 Cloud software stack designed to run on hardware
 No proprietary hardware or software requirements
 Apache License 2.0
 Components of OpenStack are as follows:
 Object Store / Swift
 Image / Glance
 Compute / Nova
 Dashboard / Horizon
 Identity / Keystone
 Network / Quantum
 Block Storage / Cinder

7. Devstack
 Shell script to build complete OpenStack development environments
 Devstack will pull code from the upstream OpenStack git repositories and deploy it on
your host or virtual machine
 Who uses Devstack?
 Developers to test changes and verify they work in a running OpenStack
deployment
 Devstack will run on Fedora 16/17/18 or Ubuntu 11.10 and above and run equally well
either directly on physical hardware or in a virtual machine
Reference - http://devstack.org/

8. Procedures Adopted
 Installing all components without clustering
 Installing LVM
 MAAS
 Trove

9. Installing LVM
 Logical Volume Management
 Includes allocating disks, striping, mirroring and resizing logical volumes
 Installation Step
 Install lvm2
 Set up hard drive partitions
 verify the newly created physical volumes
 Create Volume Group
 Create Logical Volume
 Format and Mount the logical volume

10. MAAS (Metal As A Service)
 Developed by Canonical.
 Used to manage large number of system
 Enables easy clustering of the machines
 Provides abstraction to overcome Hardware incompatibilities
 Deploys services using JuJu
Reference - http://www.ubuntu.com/cloud/tools/maas

11. MAAS (Metal As A Service)
 It turns bare metal into an elastic cloud-like resource
 Ideal where flexibility of the cloud is required
 A system that makes it quick and easy to set up the physical
hardware on which to deploy complex scalable services
 Tell MAAS about the machines you want it to manage and it will
boot them
Reference - http://www.ubuntu.com/cloud/tools/maas

12. MAAS (Metal As A Service)

13. MAAS (Metal As A Service)
 The following were the problems faced during MAAS:
 TFTP booting
 Wake on LAN
 Import of image – Limited bandwidth usage
 No GUI on MAAS server

14. Trove (Redstack)
 Trove Installation:
 Create a separate user for implementing trove on Ubuntu
 Use git command to clone the source files of trove
#git clone https://github.com/openstack/trove.git
 Install required python packages
 Go to the folder name ‘scripts’ inside trove folder
 Execute the command
#./redstack install
 We will be provided with a unique password
Reference - https://wiki.openstack.org/wiki/Trove/dev-env

15. Trove (Redstack)
 Problems Faced
 Errors during redstack installation
 Images not getting downloaded properly
 No Console available after creating the instance
 Unable to ssh Ubuntu and Fedora images
Reference - http://docs.openstack.org/developer/trove/dev/install.html

16. Trove (Redstack)
 Launching an instance (Cirros)
 Accessing an instance

17. Conclusion
The main concern was with the installation of Open Stack cloud
components which is successfully installed, up and running. At the
end of the project we have been able to understand the functioning
of Open Stack properly which was the primary goal of the project.
