The overview

What oVirt is for

oVirt provides a robust, browser-accessible management portal for orchestrating KVM-based virtualized environments. It enables administrators to provision, monitor, and manage virtual machines, hosts, storage, and networking across an enterprise-grade infrastructure directly from a web browser, streamlining the deployment and operation of virtualized workloads. The web interface serves as the primary control plane for all virtualization operations, from initial setup to daily maintenance and scaling.

Who it helps

Useful ways to use oVirt

Rapid Dev/Test Environment Provisioning

Developers can quickly provision and tear down isolated virtual machines for application development and testing, leveraging pre-configured templates via the self-service portal without direct IT intervention. This accelerates iteration cycles and ensures consistent development environment

Enterprise Virtualization Infrastructure Managemen

Operations teams utilize the web administration portal to centrally manage KVM hosts, storage arrays, and virtual networks, ensuring high availability, performance, and resource allocation for critical business applications. This includes monitoring cluster health, performing live migrations, and managing storage capacity

Cost-Effective Private Cloud Deployment

Startups can deploy a scalable, open-source virtualization platform to host their applications and services, avoiding proprietary licensing costs while maintaining full control over their infrastructure via a web-based interface. This provides a robust foundation for growth without significant upfront software investment

Quick answers

Frequently asked questions

1Is oVirt truly free to use?⌄

Yes, oVirt is 100% open-source under the Apache License 2.0, meaning there are no licensing costs for the software itself. Users are responsible for hardware, operating system licenses (for hosts/guests), and any optional commercial support from vendors like Red Hat (for Red Hat Virtualization, which is based on oVirt).

2What hypervisor does oVirt manage?⌄

oVirt is built specifically to manage KVM (Kernel-based Virtual Machine) hypervisors running on Linux hosts. It does not support other hypervisors like VMware ESXi or Microsoft Hyper-V.

3How does oVirt scale for large environments?⌄

oVirt is designed for distributed environments, capable of managing hundreds of KVM hosts and thousands of virtual machines across multiple data centers from a single management plane. Scaling involves adding more KVM hosts and storage resources to existing clusters, which are then automatically integrated and managed by the oVirt Engine.

4Can I integrate oVirt with existing IT infrastructure components?⌄

Yes, oVirt offers robust integration capabilities. This includes LDAP/Active Directory for centralized user authentication, various storage protocols (NFS, iSCSI, Fibre Channel, GlusterFS), and a comprehensive REST API for automation and orchestration with external tools like Ansible or custom scripts.

5What are the typical hardware requirements for an oVirt deployment?⌄

Minimum requirements include at least two KVM hosts with sufficient CPU (VT-x/AMD-V enabled), RAM, and local storage, plus a dedicated server or VM for the oVirt Engine (management server). Production environments typically require redundant components, high-performance shared storage, and dedicated network infrastructure for VM traffic and storage access.
