ODA- KVM Virtualization for ODA X6-2S/X6-2M/X6-2L !!

Good news! This is my 600th blog post :)

What is better than that? Let me tell you;

With the support of KVM, Oracle added the virtualization functionality to the ODA X6-2S/X6-2M/X6-2L models. (Before this, we needed to have ODA X6-2HA to make use of the virtualization capabilities of ODA)

Oracle recently announced that, from now on; we can use virtual machines on ODA X6-2S, ODA X6-2M and ODA X6-2L. This means  ODA X6-2 S/M/L environments can now be considered as Solution-in-a-box environments! This means "applications and databases all-in-one box".




The virtualization technology that we will use with these machines is Linux KVM (Kernel-based Virtual Machine)

This new virtualization option comes with the new ODA release, ODA 12.1.2.11 release.

The ODA 12.1.2.11 release is now available, and it is promising the following the new things for ODA X6-2S/M/L.
  • Support for Unbreakable Enterprise Kernel Release 4 (UEK R4) for Oracle Linux.
  • Oracle Database Bundle Patch 12.1.0.2.170418 and 11.2.0.4.170418
  • Support for Oracle KVM virtualization for Linux applications, enabling you to create isolation between your database and applications. It is not supported to run Oracle database in a guest VM with KVM environment.
So, it seems; from now on , we will reimage our ODA X6-2 machines with the 12.1.2.11 ISO images and install ODA 12.1.2.11 release on top of it to have an ODA X6 ready for supporting the KVM based virtualization.

Patch 23530609: ORACLE DATABASE APPLIANCE X6-2 S and X6-2 M 12.1.2.11.0 OS ISO IMAGE

Patch 26080577: ORACLE DATABASE APPLIANCE X6-2 S AND X6- M 12.1.2.11.0 PATCH BUNDLE DOWNLOAD

Currently, there is no instructions for creating KVM based virtual machines in Oracle Support, however; you can find some blog posts in Oracle Database Appliance blog.

https://blogs.oracle.com/oda/

Things like KVM Import an OVA Template, KVM Deploying Guest VMs with ISO, KVM Networking on ODA (Oracle Database Appliance) and Enabling KVM on ODA are alredy explained in Oracle Database Appliance blog.

The following restrictions, however; should be noted, as well :
  • only Linux OS on the guest VMs
  • It is not supported to install an Oracle database on the guest VMs
  • There is no capacity-on-demand for databases or applications running in the guest VMs
