Creating a Virtual Machine
Create a virtual machine by cloning an imported template, cloning an assembly that
contains configured virtual machines, or cloning an existing virtual machine.
A virtual machine is a software emulation of a computer system that is granted virtual
resources, and can be started, stopped, and restarted independently.
When you clone a template, the template is imported as an archive, unpacked, and
stored as a virtual machine configuration file with disk images. The disk images are
cloned to create a new instance in the form of a virtual machine.
Instead of creating a complete clone of a template or assembly, you can create a snap
clone, which contains only the metadata defined for the virtual machine.

Configuring a Virtual Machine
Use the
oakcli configure vm
command to configure a virtual machine on Oracle
Database Appliance Virtualized Platform.
Include a
-prefnode
clause, to identify the node where you want the virtual machine
to run by default and a
-failover
clause to indicate if you want the virtual machine to
use the other node when the preferred node is not available (either at startup or while
already active).
If you reconfigure a virtual machine that is currently running, then your changes do not
take effect until you stop and restart the virtual machine.
Table 12-1 Parameters Available for Configuring a Virtual Machine
