Configuring the Oracle VM Environment
Configuring an Oracle VM environment includes the following:
- Discovering servers
- Creating and configuring multiple networks
- Discovering and configuring storage
- Creating a storage repository
- Creating a server pool
- Creating virtual machines.
Login to the Oracle VM Manager using the below web address format
For example: http://vmmanager.bdcdb.com:7001/ovm/console
Discovering Oracle VM Servers
- In the Oracle VM Manger console click the Servers and VMs tab.
Figure 1: Oracle VM Manger
- Click Create Server pool from the tool bar and enter the Server pool name and virtual IP address. Select the Clustered Server Pool to enable clustering of the Oracle VM Servers within the server pool in order to enable HA.
Figure 2: Create Server pool
- Select Physical disk in the storage for server pool and click Storage Location and select the Physical disk for the server pool and click OK
Figure 3: Select Physical disk in the storage
Figure 4: Select the Physical disk for the server pool
- Click next to add servers to the server pool.

Creating a Storage Repository and Adding Resources
A storage repository is where Oracle VM resources such as templates for virtual machine creation, virtual machine assemblies, ISO files and shared virtual disks will reside.
NOTE: A storage repository should be at least 10GB in size. In addition to this minimum size requirement, you should include enough storage space for virtual machines, templates, ISO files and other virtual machine resources.
To create storage Repository
- In the Oracle VM manager, click Repositories tab
Figure 7: Oracle VM manager
- Click Create New Repository (plus sign icon) from the tool bar and enter the repository name and repository location. If you select physical disk as a repository location, select the appropriate server pool that the repository should reside.
Figure 8: Create New Repository
- Click on select physical disk to search for the location. In the select physical disk window, select physical disk for repository and click Next.
Figure 9: Click on select physical disk to search for the location
- Click next to present the Oracle VM servers to the repository.
Figure 10: Oracle VM servers to the repository
- Click Finish and new storage repository is displayed in the Repositories tab.

Importing ISO resource
Create an installation directory and copy all the operating system ISO files into the directory.
NOTE: The directory should be made available via a NFS, HTTP or FTP share.
Refer to "Virtual Machine Installation Media" for performing the NFS/ HTTP/FTP share
To import an ISO file:
- Click the Repositories tab. Select the repository where the ISO files are stored. Select ISOs in the navigation tree. Select Import ISO... button in the toolbar in the management pane.
Figure 12: Select ISOs in the navigation tree
- The Import ISO dialog box is displayed.
Figure 13: Import ISO
Provide the ISO location which is a HTTP/FTP share and Click OK.
The ISO file is then uploaded to the repository as shown below.
Provide the ISO location
VNICs) can be used by the virtual machines as network cards. A VNIC can be created by defining a range of MAC addresses to use for each VM. Each MAC address corresponds with a single VNIC, which is used by a virtual machine.
To create VNICs
- In the Oracle VM Manager, click the Networking tab. Select the Virtual NICs sub tab
- In the Create VNICs tab, click AutoFill to get the next MAC address and select the number of VNICs to be created.
- Click create to generate the VNICs.
Figure 15: Creating VNICs
Creating Virtual Machines
Virtual machines can be created using the following methods.
- ISO files
- VM Templates
Installing single node standalone database on the Oracle VM
- Launch the VM console from the OVM Manager
