In my new role at Keste, I am tasked with staying on the bleeding edge of software release cycles, so that we can be knowledgeable and authoritative about technology when we engage with customers. One of the areas where Keste leads is on Oracle’s Virtualization Offerings. So I will be posting more and more content with respect to those offerings.
Today I will be documenting the steps to install Oracle VM Manager 3.1.1. Oracle VM (OVM) is a Xen-based Virtualization Technology. An OVM Deployment consists of the OVM Server (the bare metal hypervisor) and the OVM Manager, the application stack which manages the afforementioned hypervisors (organized into Server Pools).
The OVM Server installation is really no different from a standard Oracle Linux, or even RHEL install, so I am not going to bother writing that one up unless something changes architecturally.
Now to get started I have pre-provisioned a Oracle Linux Server (5.6) machine which will accept the OVM Manager application.
# cat /etc/issue Oracle Linux Server release 5.6 Kernel \r on an \m
Download Oracle VM Manager 3.1.1 from http://edelivery.oracle.com/oraclevm
I have an NFS mount which holds my media, but the process is the same if you are using local storage. We want to mount the iso image file into a folder (/mnt in my case)
# mount -o loop /nfsmount/OracleVM-Manager-3.1.1.iso /mnt # cd /mnt # ls components EULA oracle-validated.params runInstaller.sh TRANS.TBL createOracle.sh LICENSE ovmm-installer.bsx runUpgrader.sh upgrade
Prepare Machine for Installation
Oracle VM Manager includes a script which does most of the dirty work for us… This will create the users/groups, folders, and iptables rules needed by OVM. If you are going to be using an external firewall, then these are the ports you will need to open on your firewall (bold denotes client to management server communications – remainder are management server to hypervisor).
tcp: 7001–7002, 15901, 54321-5432
Luckily though all we need to do is execute the below script…
# ./createOracle.sh Adding group 'oinstall' with gid '54321' ... Adding group 'dba' Adding user 'oracle' with user id '54321', initial login group 'dba', supplementary group 'oinstall' and home directory '/home/oracle' ...

The documentation mentions libaio, bc, and unzip as prerequsites. My install already included this, so installing them was redundant.
# yum install libaio bc unzip Loaded plugins: rhnplugin, security This system is not registered with ULN. ULN support will be disabled. Setting up Install Process Package libaio-0.3.106-5.x86_64 already installed and latest version Package libaio-0.3.106-5.i386 already installed and latest version Package bc-1.06-21.x86_64 already installed and latest version Package unzip-5.52-3.0.1.el5.x86_64 already installed and latest version Nothing to do.
Install the Oracle VM Manager Software
Here we simply execute the installer script and follow the prompts. Notice the first prompt asks us the installation type. I am using Demo, this will install the XE database, and configure OVM Manager to use that. This is not a support configuration. If you plan on using this stack in production you will need to install using option two, which will not install a database but rather will require that you connect to a pre-created database, on either the local or a remote server.
# ./runInstaller.sh Oracle VM Manager Release 3.1.1 Installer Oracle VM Manager Installer log file: /tmp/install-2012-05-09-162921.log
Please select an installation type: 1: Demo 2: Production 3: Uninstall 4: Help Select Number (1-4): 1 Starting demo installation ...
Just some warnings about the XE database. If you are installing this for production, make sure you heed this warning.
The Demo installation type will use an XE database. The usage of XE is for *demo purposes only* and is not supported for production. Please *do not* plan to start with XE and migrate to a supported version of the database as this may not be possible. For production environments or any long term usage please use the "Production" option with an SE or EE database. 1: Continue 2: Abort Select Number (1-2): 1
Now we are going to enter the password to be used for all purposes. You must have a password with only alpha-numeric characters, no special characters here, you also must have both upper and lower case, with a length of 8.
Verifying installation prerequisites ... One password is used for all users created and used during the installation. Enter a password for all logins used during the installation: <enter password here> Enter a password for all logins used during the installation (confirm): <re-enter password here>
Now that we are ready to begin, this is your last chance to back out.
Verifying configuration ... Start installing the configured components: 1: Continue 2: Abort Select Number (1-2): 1
Beginning the installation, now we just wait.

I ran into a problem here. I used a password which I believe met all of the requirements, 1 upper-case, 1 number, 8 lower-case, no special characters. However the install failed here with a failed authentication error. I suspected this had something to do with differing password requirements for various components. I tried re-running the installation with a 8 digit password, that met the requirements, but it was having a problem since the Database and Java were already installed. I got around this by choosing the uninstall option when first executing the install script. Then the subsequent run with the 8 digit-only password worked an example of a password which meets the requirements would be Gpdf5098.

Well the installation is nearly done. It is doing the last step of the installation, before giving you the information you need for accessing the GUI.
Installation Summary -------------------- Database configuration: Database host name : localhost Database instance name (SID): XE Database listener port : 1521 Application Express port : 8080 Oracle VM Manager schema : ovs Weblogic Server configuration: Administration username : weblogic Oracle VM Manager configuration: Username : admin Core management port : 54321 UUID : 0004fb00000100004ac53f7c774415a7 Passwords: There are no default passwords for any users. The passwords to use for Oracle VM Manager, Oracle Database 11g XE, and Oracle WebLogic Server have been set by you during this installation. In the case of a default install, all passwords are the same.
Oracle VM Manager UI: http://ovmmgr.allanglesit.com:7001/ovm/console https://ovmmgr.allanglesit.com:7002/ovm/console Log in with the user 'admin', and the password you set during the installation. Please note that you need to install tightvnc-java on this computer to access a virtual machine's console. For more information about Oracle Virtualization, please visit: http://www.oracle.com/virtualization/ Oracle VM Manager installation complete. Please remove configuration file /tmp/ovm_configD62uIU.
So now with the completion of the install we can see that the site is available at both an http and an https site running on ports 7001 and 7002 respectively.
Now that we have laid this foundation we can start to get into some of the neat processes around using this particular stack.
