In general, Oracle VM HA enables the restart of an Oracle VM guest on either the same physical machine or a different machine, if more than one physical machine is available in the server pool. However, in any case, Oracle VM would operate on the VM guest as a whole, restarting whatever is running within it. The reason is that the Oracle VM guest is usually unaware of the applications running in the virtualized environment as much as the application is typically unaware of the Oracle VM guest it is running in. For a fast, finer grained.
