1.1 Planning Your Oracle VM Deployment

To install Oracle VM, you must install at least one Oracle VM Server and one instance of Oracle VM Manager. Your Oracle VM Server can be on either x86 hardware or SPARC hardware. Oracle VM Servers in a server pool must be of the same type, either x86 or SPARC. You cannot mix x86 and SPARC servers in the same server pool; however Oracle VM Manager can manage server pools of different types.

If you are planning to install Oracle VM in a production environments, the following requirements apply:

  • Oracle VM Manager and Oracle VM Server versions should be the same whenever possible. You can use Oracle VM Manager to manage Oracle VM Servers on a different, earlier patch level of a release – for example: Oracle VM Manager 3.4.5 with Oracle VM Server 3.4.2. However, it is recommended that you maintain the same patch level to ensure full compatibility with the latest functionality.

    To facilitate the upgrade of your environment, you can temporarily use Oracle VM Manager Release 3.4.x in combination with Oracle VM Servers at Release 3.2.10, 3.2.11 or 3.3.x. However, in such a mixed environment you can no longer change the configuration of the servers running an older software release; server management is restricted to presenting storage repositories and performing virtual machine operations. You should proceed with the upgrade of your Oracle VM Servers as soon as possible, so that the installed release matches Oracle VM Manager again, and full management functionality is restored.


    Beginning with Release 3.4.6, upgrades from Oracle VM Server for x86 at Release 3.2.10 or 3.2.11 and Oracle VM Agent for SPARC at Release 3.3.1 are not supported. Users on these older server releases must first upgrade to a supported version (e.g. 3.4.5) before upgrading to a later version.


    As of Release 3.4.5, Oracle VM Manager uses the TLSv1.2 protocol by default. To be able to temporarily manage Oracle VM Servers at Release 3.2.10, 3.2.11 or 3.3.x, and Oracle VM Agent for SPARC at Release 3.3.1, you can enable the TLSv1 protocol, which is less secure. For instructions, see Section 7.6, “Enabling the TLS Version 1 Protocol” in the Oracle VM 3.4 Installation and Upgrade guide.

  • A minimum cluster of three Oracle VM Server nodes in each server pool is strongly recommended for high availability (HA). If one node in the cluster experiences a hardware failure or is shut down for maintenance, failover redundancy is preserved with the other two nodes. Having a third node in the cluster also provides reserve capacity for production load requirements.
