What is oVirt?
oVirt is an open-source virtualization management platform that provides a self-hosted infrastructure for managing virtual machines, containers, and storage. It is designed to be highly scalable, reliable, and secure, making it a popular choice among organizations looking for a cost-effective alternative to proprietary virtualization solutions.
One of the key benefits of oVirt is its ability to provide a centralized management interface for virtualized resources, including VMs, containers, and storage. This allows administrators to easily manage and monitor their virtualized infrastructure, reducing the complexity and cost associated with managing multiple virtualization platforms.
Main Features of oVirt
Some of the main features of oVirt include:
- Support for multiple hypervisors, including KVM, Xen, and VMware
- Integration with a variety of storage solutions, including local, shared, and cloud-based storage
- Support for live migration of VMs between hosts
- Centralized management interface for VMs, containers, and storage
Installation Guide
Step 1: Prepare the Environment
Before installing oVirt, you will need to prepare the environment by setting up the necessary infrastructure, including the hypervisor, storage, and network.
This includes:
- Installing the hypervisor on the host machines
- Configuring the storage infrastructure, including setting up the storage pool and allocating storage to the VMs
