3 AIOUG is a non profit organization started by like minded users who think such a community is required in India where the amount of Oracle user base is humongous. The idea of this group is to share what the Oracle users have learned from using Oracle technology over the years with fellow users who have similar interest. AIOUG is registered as a Society under the Karnataka Societies Registration Act, 1960 vide Society Number SOR- SJR-35/07-08 dated 21st September, 2007.

7 General Discussion on Virtualization. What is Virtualization? What is Hypervisors? & Types Oracle VM Virtual Box Why is virtualization useful?

8 Virtualization technology emulates real or physical computing resources, such as desktop computers and servers, processors and memory, storage systems, networking, and individual applications. Types Hardware Virtualization Full Software Virtualization Para virtualization Hardware-assisted software virtualization Component or resource virtualization

9 A hypervisor, also called a virtual machine manager, is a program that allows multiple operating systems to share a single hardware host. Each operating system appears to have the host's processor, memory, and other resources all to itself. However, the hypervisor is actually controlling the host processor and resources, allocating what is needed to each operating system in turn and making sure that the guest operating systems (called virtual machines) cannot disrupt each other.

10 Running multiple operating systems simultaneously Easier software installations Infrastructure consolidation Testing and disaster recovery

11 For Windows, Linux, Solaris and Mac Hosts Leverage existing hardware and skillsets Huge Guest Coverage Easy to install and use Fast and powerful Free for Personal Use

12 Web Service interfaces COM/XPCOM interfaces Python interfaces and interactive shell Command line interface VBoxManage Pluggable Virtual Device architecture and APIs

13 Powerful command line tools # VBoxManage Python shell # python vboxshell.py

14 Organize VM groups to manage and control guests collectively Nested groups Create Express mode guest creation New Guest types Start Launch groups Launch headless Stop Stop vm or groups using Shutdown, Suspend, Poweroff

17 Networking modes NAT (client) Bridged (full network citizen) Internal Host-only networking Port-forwarding 32-bit or 64-bit Servers Headless-mode Servers

18 DEVELOPER/SYSTEM ARCHITECT YOU NEVER KNOW WHEN A CHANGE IN THE ENVIRONMENT OR STACK IS GOING TO BITE YOU. YOU CAN SOMETIMES SPEND SO MUCH TIME DIAGNOSING WHAT CHANGED.

19 Testing Create a snapshot Modify guest (e.g. patches, install apps, etc.) Revert back to initial state Branching Use different software levels of the guest (e.g. IE5, IE6, IE7,...) Backup Revert to a pristine base (e.g. viruses,...)

20 Use cases: Backup: create a full copy of an existing VM to have a backup Branching/Testing: like Snapshots Template: allow to create several VMs (which could than be modified) from one base state Replication: the same VM could be started more than once after cloning (e.g. clusters, grids)

21 VIRTUAL APPLIANCES OR VM TEMPLATES SO OFTEN PROBLEMS ARE INTRODUCED BY PEOPLE NOT DEPLOYING OUR STUFF CORRECTLY. BUT WE CAN'T SHIP A HUMAN BEING WITH EVERY COPY OF THE SOFTWARE.
