What is oVirt?

oVirt is a complete virtualization management platform, licensed and developed as open source software. oVirt builds on the powerful kernel based virtual machine (KVM hypervisor) and on the RHEV-M management server, released by Red Hat to the open source community.

What's included?

  • Rich web-based user interfaces for both admin and non-admin users
  • Live migration of virtual machines and disks between hosts and storage
  • Integrated management of hosts, storage, and network configuration
  • High availability of virtual machines in the event of host failure

Case Studies

Florida State University RCC

Florida State University’s Research Computing Center (RCC) provides the university’s academic community with access to a virtual machine cluster. It is used for basic data services, collaborative applications, firewall installation, and other self-managed services.

In 2016, RCC successfully migrated their virtual machine cluster to oVirt. The oVirt-powered cluster is currently serving 60 users across 20 academic departments.

Alter Way

Meet Alter Way, a French hosting company who deploys oVirt in production for their clients, because "it allowed us to scale up as well as scale out our client workloads".

The main points which swayed their decision? "A very active community, an ambitious technical roadmap with regular releases, and the involvement of companies including Red Hat, Intel, NetApp, Cisco and IBM reassured us that the project would be around for the duration."

Brussels Airport Company

Find out how the Brussels Airport Company keeps a vital transportation and cargo center moving by managing their virtual machines with oVirt.

Faced with an opportunity to take the approximately 150 virtual machines housed on 30 Solaris machines and manage them with another virtual datacenter management tool, the Brussels Airport IT team went with oVirt running atop CentOS.

LVM Configuration the Easy Way

Now oVirt features a simple way to prevent a host from scanning and then activating logical volumes that are not required directly by the host. In particular, the solution addresses logical volumes on shared storage managed by oVirt, and logical volumes created by a guest in oVirt raw volumes. Why is a solution required? Because scanning and activating other logical volumes may cause data corruption, slow boot, and other issues.

The solution is configuring an LVM filter on each host, which allows LVM on a host to scan only the logical volumes required directly by the host. To achieve this, we have introduced a vdsm-tool command, config-lvm-filter, that will configure the host for you.

Engine XML Brings a Smoother Flow of Data Into oVirt

on November 8, oVirt 4.2 saw the introduction of an important behind-the-scenes enhancement.

The change is associated with the exchange of information between the engine and the VDSM. It addresses the issue of multiple abstraction layers, with each layer needing to convert its input into a suitably readable format in order to report to the next layer.

This change improves data communication between the engine and Libvirt - the tool that manages platform virtualization.
