As shown in the support matrix for OVM 2.2.2, RHEL/OL6 is supported as a paravirtualized VM.

What is the procedure to perform this conversion and the dependencies that are required.

The following procedure describes how to reconfigure an Oracle VM 2.x Oracle Linux 6 (OL6) guest Virtual Machine (VM) from fully/hardware virtualised (HVM) to paravirtualised (PVM).

Conversion of an Oracle Linux (OL) guest from HVM to PVM requires modification of the guest itself, as well as to the Oracle VM guest configuration.

All changes required to be made to the Oracle VM guest configuration file (vm.cfg) are performed.

Users are strongly advised against manual modification of Oracle VM Server and guest configuration files.

Do not attempt to use the described procedure to convert guests of other Oracle Linux versions.
