Review the concepts and procedures for Oracle Database Appliance Virtualized Platform.
Topics:
KVM virtualization uses a kernel-based virtual machine (KVM) to create a virtualized environment for your Linux applications.
Beginning with Oracle Database Appliance 12.1.2.11.0, the required RPMs are included in the Oracle Database Appliance patch bundle. When you upgrade to Oracle Database Appliance 12.1.2.11.0, the Oracle Linux KVM hypervisor is installed as part of the Oracle Linux kernel and uses CPU extensions (HVM) for virtualization. The Linux KVM is a Type II hypervisor, which means that it is one layer above the operating system. When you run your Linux applications in a virtualized environment, you can isolate your database from your applications. One of the advantages to isolating the applications is that you can update your Oracle Database without impacting the applications.
All virtual machines, or guests, are Oracle Linux operating systems and only Linux applications are supported in the KVM. You cannot deploy an Oracle Database in the KVM. Oracle Databases must run on the base Oracle Linux operating system.
