OVM, Oracle Linux, KVM

What is Oracle Linux?

Oracle Linux is the Linux distribution from Oracle. To be more precise, Oracle Linux (earlier called Oracle Enterprise Linux) is a binary clone of Red Hat Enterprise Linux (RHEL) distribution.

Some points to note:

  • RHEL is the upstream distribution
  • Oracle downloads RHEL, removes the trademarks, compiles it & creates a new distribution
  • Users can download the Oracle Linux distribution for free
  • The creation of a binary clone of RHEL is legal under the different open source license agreements covering the Linux distributions.

Why is Oracle Linux important?

Apart from the compatibility with RHEL, Oracle Linux is important for license management.
Oracle has approved KVM – the virtualization technology within Linux as a hard partitioning technology. But there is a catch – this is approved only if the customer is using Oracle Linux.

What is KVM?

Kernel-based Virtual Machine (KVM) is an open-source virtualization technology built into Linux. KVM is the hypervisor embedded within Linux that allows a bare-metal host machine to run multiple guests or Virtual Machines (VMs).

Oracle allows KVM to be used as a ‘hard-partitioning’ technology if Oracle Linux is used.
