Creation of virtual machines is the most elemental function you will use within your Oracle VM Manager. However, in order to create virtual machines, a server pool must be created to host your virtual machines. A server pool can be thought of as a container in which to hold one or more physical servers. Once a server pool is created, virtual machines can be hosted by one of the physical servers within the server pool. Virtual Machines by default are hosted in a round-robin fashion making sure the servers within your pool are properly load balanced. However, if there is a particular need for a VM to be hosted on a particular server within your server pool you can manually set this feature using the ‘Preferred Server’ section when creating a virtual machine. Manually assigning a VM to a particular server is not recommended because you will lose high availability.
The steps to create a Server Pool are as follows:
1. Select the tab labeled ‘Server Pools’
2. On the right corner select the button labeled ‘Create Pool’
3. On the section labeled ‘Create Server Pool’ please enter the name of your server pool, the server pool virtual IP, and make sure to set High Availability Mode to ‘Enabled.’ The server pool virtual IP will allow the ability to enable high availability. If a virtual IP is not entered, the High Availability Mode will be disabled.
4. On the section labeled ‘Server Details’ add the servers you wish to register within your server pool. Once you have entered a server’s credentials select the ‘Add’ button on the right corner. It is important to note that each server pool requires one Master node, at least one Utility Server, and at least one Virtual Machine Server.
For more information on what exactly is a master, utility and virtual server please refer to the master book list found at http://download.oracle.com/docs/cd/E15458_01/nav/portal_booklist.htm
5. On the User information section please fill out the appropriate information and click Next.
6. On the Confirmation Summary, please review the server pool details and, if correct, click Finish.
