Prev	Chapter 3 Managing the Oracle VM Virtual Infrastructure	Next

The Oracle VM Manager Web User Interface is provided without any software limitation to its functionality. Once your appliance has been provisioned, the Oracle VM environment is fully configured and ready to use for the deployment and management of your virtual machines. In this section, the operations that are explicitly not permitted, and those that may be attempted with due care, are presented as guidelines and limitations that should be followed when working within Oracle VM Manager.

The following actions must not be performed, except if Oracle gives specific instructions to do so.

Do Not:

attempt to discover or modify or remove servers or their configuration;
attempt to add or modify or remove server pools or their configuration;
attempt to move servers out of the existing server pool;
attempt to add or modify or remove affinity groups or server processor compatibility groups;
attempt to modify or remove the existing repository named Rack1-repository, or the local disk repositories;
attempt to delete or modify any of the preconfigured networks;
attempt to connect virtual machines to the appliance management network;
attempt to add or configure VLAN Groups, except to add VLAN tags to the default VLAN Group configuration;
attempt to modify or delete any existing Storage elements that are already configured within Oracle VM;
attempt to configure global settings in the Tools and Resources tab, such as the NTP or YUM Update configuration.

While unlikely to cause a problem with your appliance, the following actions are not recommended:

Not Recommended:

configure additional external storage for Oracle VM Manager;
add an additional repository within Oracle VM Manager;
add or configure additional networks within Oracle VM Manager;
use the Oracle VM Manager Command Line Interface or Utilities.

If you ignore this advice, the Oracle Virtual Compute Appliance automation, which uses specific naming conventions to label and manage assets, may fail. Out-of-band configuration changes would not be known to the orchestration software of the Oracle Virtual Compute Appliance.
