Removal of Pre-Existing MySQL Installations

If you have an existing MySQL installation on the system where you intend to install Oracle VM Manager you must backup your databases and uninstall it. Oracle VM Manager requires exclusive use of MySQL due to the specific tuning parameters that it applies to the configuration. Oracle VM Manager uses MySQL Enterprise Edition on a non-standard port. The licensing of the MySQL Enterprise Edition provided with Oracle VM Manager grants exclusive use to Oracle VM. You must not use the MySQL server provided for any other purpose. If an existing MySQL installation is present on the system, the installer exits with an error message informing you that you must remove this before continuing with the installation.
