Friday Tips #33

Happy Friday, everyone!

Our tip this week is from an excellent white paper written by our own Greg King titled Oracle VM 3: Building a Demo Environment using Oracle VM VirtualBox. In it, Greg gives you everything you need to know to set up Oracle VM Server inside of Oracle VM VirtualBox for testing and demoing. The section we're highlighting below is on how to configure the network interfaces of your virtual machines:

VirtualBox comes with a few different types of network interfaces that can be used to allow communication between the VM guests and the host operating system, including network interfaces that will allow the VM guests to communicate with local and wide area networks accessed from your laptop or personal computer. However, for the purpose of the demonstration environment we will limit the network communication to include access just between your desktop and the virtual machines being managed by VirtualBox.

The install process for Oracle VM VirtualBox creates a single host-only network device on your laptop or personal computer. Using the host-only network device will allow you to open a browser on your desktop to access the Oracle VM Manager running within the VirtualBox VM guest. The device will only allow network traffic between the VM guests and your host operating system, but nothing outside the confines of your laptop or personal computer.

We will need to add a second host-only network since the Oracle VM Server appliance has both eth0 and eth1 configured. You can choose to use eth1 on the Oracle VM Servers or not use them – the choice is yours. But, at least the host side network device will exist if you decide to use it.

Greg goes on to describe in detail how to setup the network interfaces, so you can head on over to the paper and get even more info.

See you next week!

Designing, Creating and Testing an Oracle VM 3.2 Environment

We just published a new technical white paper written by Wayne Lewis, Principal Sales Consultant from Oracle VM and Oracle Linux sales team.

The paper here focuses on the Oracle VM Server for x86 and Oracle VM Manager. This document describes a plan you could follow to ensure that your Oracle VM deployment is organized, repeatable and tested before you mark it ready for production. The plan is broken down into three key stages, each of which may touch many aspects of the overall deployment.

  • Stage 1: Designing your Oracle VM environment
  • Stage 2: Creating your Oracle VM environment
  • Stage 3: Testing your Oracle VM environment

Contained within this document are a number of tips, hints, instructions and even a test plan check-sheet for you to use when planning, building and testing your Oracle VM environment. At the end of the document are several Appendices containing useful reference material related to the deployment of Oracle VM, including some reference configuration files.

The white paper is definitively a handy guide to help you design, create and test your Oracle VM 3.2 environment. For the latest information, best practices white papers and webinars, please visit http://oracle.com/virtualization.

Friday Tips #12

Our tip this week is about the newly released Oracle VM 3.2. For some background, you might also want to check out this related tip on updating Oracle VM Manager.

Question:
How do I get started with the command line interface for Oracle VM Manager?

Answer by Gregory King, Principal Best Practices Consultant, Oracle VM Product Management:
Oracle VM 3 ships with an automation tool that system administrators are going to love! Beginning with the latest version of 3.2, our Oracle VM 3 product comes with a built-in command line interface (CLI) that allows system administrators to create automated solutions using their favorite shell or scripting language. For example, you can create a bash or ksh script using calls to the CLI to gather information about objects and attributes managed by the Oracle VM Manager. You can also include CLI calls to change objects and attributes as well as initiate tasks such as putting a server into maintenance mode and then starting a software update using our built-in Server Update Manager.

Check Your Access to the CLI
The CLI is started automatically when the Oracle VM Manager is started during boot or whenever you execute “service ovmm start” on the server where Oracle VM Manager is installed. Test the ability to connect to the CLI first by logging in using ssh. You can execute the ssh session from any server with an ssh client – you should really test the login from the server where the automation scripts will reside. Perhaps you want to write the scripts and keep them on the same server where Oracle VM Manager is installed or perhaps you want to keep the scripts on a management/administration server where you keep all your other management scripts – the choice is really up to you.

Let’s assume for our example you are going to keep the scripts on a Linux server named “myserver”. Simply execute the ssh command shown below to test your login.  The CLI will prompt you for a password – this is the same password you use for the admin user when you log into the Oracle VM Manager.

You can see a list of available commands by typing either help or “?” at the command prompt as shown below.

You will most likely want to add ssh keys on the Oracle VM Management server to allow your script to execute without prompting for a password.  If your scripts are going to be executed as root from myserver, then add the public keys from myserver:/root/.ssh/*.pub into a single file named ovmcli_authorized_keys and copy the file to the oracle home directory on mymanager:/home/oracle/.ssh/ovmcli_authorized_keys. Make sure the ovmcli_authorized_keys file is owned by oracle and the group is dba – I always change the permissions to 644, but I’m not sure that is actually needed. The CLI will prompt for a password the first time after copying the file to that directory, but will not prompt again afterwards.

Thanks Greg. For more information on Oracle VM 3.2, have a read through Honglin's excellent blog entry on this very blog.

We'll see you next week!

Announcing Oracle VM 3.2 - Delivers Unified Management and Enhanced Automation Capabilities for x86 Servers and SPARC Servers

We are pleased to announce Oracle VM 3.2, which delivers unified management and enhanced automation capabilities for x86 servers and SPARC servers. Read the blog here for a detailed list of the new features.

The new software highlights:

  • Unified server virtualization management for x86 and SPARC
  • MySQL database support as the management database with automated backup
  • Greater automation with Oracle VM Manager Command Line Interface (CLI)
  • Lots of manageability, usability, scalability and robustness improvements to help users manage their large and growing environments
One of the key enhancements is the ability to discover and manage Oracle VM Server for SPARC, thus creating a single management console for both SPARC and x86 virtual machines. Users can create SPARC server pools, virtual machines, as well as manage networking and storage in the same way this is done for x86 environments. In addition, SPARC users can quickly provision new virtual machines from assemblies and template in the same simple way as it is done for x86. This allows deploying applications in minutes and significantly improves productivity for SPARC users.

Please review the white paper below to get started with the new capability of Oracle VM Manager:

The nice thing about the unified management capability from Oracle VM Manager is the common management framework, and it is the same set of APIs that apply to both x86 and SPARC server virtualization. For example,  full command-line support enables easy automation at the Oracle VM Manager level. Oracle VM Manager Command Line Interface (CLI) supports the same functions as the Oracle VM Manager browser interface. Common tasks can be scripted and fully automated, saving time and lowering the risk of human error. You learn one set of APIs, but you have the flexibility to manage both x86 and SPARC server virtualization.

You may want to enroll the training courses offered by Oracle University to get more from your Oracle VM infrastructure:
