Access to the Oracle VM Manager web user interface, command line interface and web services API is provided without restrictions. The configuration of Oracle Private Cloud Appliance (PCA) components within Oracle VM Manager is automatic and handled by the Oracle PCA provisioning process. Altering the configuration of these components directly within Oracle VM Manager is not supported and may result in the malfunction of the appliance.
Here is a non-exhaustive list of critical limitations that are known to be violated regularly, which results in severe system configuration problems and significant downtime:
DO NOT rename host names of compute names or other Oracle PCA components.
DO NOT rename server pools.
DO NOT rename built-in repositories.
DO NOT rename existing networks or modify their properties (VLAN tag, MTU, and so on), except as documented explicitly in the Oracle Private Cloud Appliance Administrator's Guide.
The appliance controller software enables customization of networking, external storage connectivity and server pools – known as tenant groups in Oracle PCA. The resulting Oracle VM configurations also must not be altered within Oracle VM Manager.
Use of Oracle VM Manager in the context of Oracle Private Cloud Appliance should be limited to the management and creation of virtual machines.
Configuring additional storage, creating repositories, and setting up additional networks specifically for the use of virtual machines is possible. However, this should be done carefully, to avoid disrupting the configuration specific to the Oracle PCA.
Management of virtual machines and your Oracle VM environment is achieved using the Oracle VM Manager Web UI (User Interface). While Oracle VM Manager does provide a command line interface and web services API, use of these on your Oracle PCA should only be attempted by advanced users with a thorough understanding of Oracle VM and the usage limitations within an Oracle PCA context.
The information provided in here, is a description of the Oracle VM Manager Web UI within the context of the Oracle PCA. Where particular actions within the Oracle VM Manager Web UI are referenced, a link to the appropriate section within the Oracle VM Manager User's Guide is provided. The complete Oracle VM Manager User's Guide is available at this URL: https://docs.oracle.com/cd/E64076_01/E64082/html/index.html.
When consulting the Oracle VM documentation directly, keep in mind the limitations imposed by using it within Oracle PCA. More details about the use of the Oracle VM documentation library can be found in About the Oracle VM Documentation Library.
New users of Oracle VM who want to learn the fundamentals of creating and maintaining a virtualized environment should consult the Oracle VM Concepts Guide. It describes the concepts on which the Oracle VM components and functionality are based, and also links to operational procedures in the Oracle VM Manager User's Guide.
The Oracle VM Manager Web UI is available at the virtual IP address that you configured for your management nodes during installation. This virtual IP address is automatically assigned to whichever management node is currently the master or active node within the cluster. If that management node becomes unavailable, the standby management node is promoted to the active role and takes over the IP address automatically. See Section 1.5, “High Availability” for more information on management node failover.
The Oracle VM Manager Web UI is configured to listen for HTTPS requests on port 7002.
