Oracle Linux Virtualization Manager (OLVM) is a powerful, open-source server virtualization management platform that simplifies the deployment, monitoring, and management of Kernel-based Virtual Machines (KVMs) in an Oracle Linux environment. It offers enterprise-grade performance and is fully supported by Oracle

Key Features and Benefits:

  • Open Source and Cost-Effective: OLVM is based on the open-source oVirt project, making it a cost-effective solution with no licensing fees.
  • Centralized Management: Provides a centralized web-based interface (Administration Portal) for managing the entire virtual environment, including hosts, virtual machines (VMs), storage, and networks.
  • Simplified VM Management: Streamlines VM creation, cloning, migration, snapshots, and resource allocation.
  • High Availability and Live Migration: Supports live migration of VMs between hosts with minimal downtime, ensuring high availability for critical applications.
  • Scalability: Designed to handle large-scale virtualization deployments, allowing you to manage numerous hosts and VMs efficiently.
  • Integration with Oracle Linux: Tightly integrated with Oracle Linux, leveraging the stability and security of the underlying operating system.
  • Enterprise-Grade Support: Backed by Oracle’s comprehensive support organization, providing access to expertise and resources for troubleshooting and issue resolution.
  • Hyperconverged Infrastructure (HCI) Support: Enables the creation of HCI solutions by combining compute and storage resources on the same nodes.
  • REST API: Offers a RESTful API for automation and integration with other management tools.

Architecture:

OLVM consists of two main components:

  • Administration Portal: A web-based interface for administrators to manage the virtual environment.
  • VM Portal: A lightweight web interface for end-users to manage their own VMs.

Use Cases:

  • Server Consolidation: Reduce hardware costs by running multiple VMs on a single physical server.
  • Development and Testing: Create isolated environments for developing and testing applications.
  • Cloud Computing: Build private or hybrid cloud environments.
  • Disaster Recovery: Implement disaster recovery solutions by replicating VMs to a secondary site.

OLVM vs. Other Virtualization Platforms

Getting Started with OLVM:

To get started with OLVM, you can follow these steps:

  1. Download and Install: Download the OLVM installation packages from the Oracle website and install them on your Oracle Linux system.
  2. Configure Hosts: Add your KVM hosts to the OLVM environment.
  3. Create Storage Domains: Define storage locations for VM images and data.
  4. Create Networks: Configure virtual networks for VMs to communicate with each other and the outside world.
  5. Create VMs: Create and configure VMs based on your requirements.
