Oracle’s virtualization technology of choice is Oracle Linux KVM (Kernel-based Virtualization Machine), which is the standard hypervisor used in Oracle Cloud Infrastructure, Exadata, and several other Oracle products. Oracle Database Appliance (ODA) will complete the transition from the Xen-based Oracle VM to Oracle Linux KVM in the next major ODA SW release to provide customers with the latest advancements in virtualization technology.
One key question that comes up is regarding support for OVM on ODA and how that is impacted by the end of support for OVM itself beyond March 2021. I want to clarify here that the end of support for OVM in March has no bearing on the supportability of OVM on ODA. However, some key points need to be highlighted concerning OVM on ODA support.
We began the transition of the hypervisor technology to KVM starting with the ODA 19.9 release (supported KVM for applications), continued with ODA 19.10 (support Oracle DB running as KVM guests with hard partitioning, but with some limitations) and the transition to KVM will be complete with the ODA 19.11 release.
ODA customers can refer to the following MOS note to get premier support status for their specific platform. Below is a screenshot of the Oracle Database Appliance premier support status table.
