oVirt Node

This is the main entry page for using oVirt Node.


The oVirt Node sub-project is geared towards building a small, robust operating system image. It uses minimal resources while providing the ability to control virtual machines running upon it.

After installing oVirt Node the host can directly be added to oVirt Engine and be used as a host to run your Virtual Machines.

For installation Node now relies on Anaconda - the installer used for installing Fedora, CentOS and Red Hat Enterprise Linux. Formerly Node used a specialiced TUI installer to perform the installation.

For administration Node is now leveraging Cockpit formerly the administration was performed by a specialiced administration TUI.


  1. Download the oVirt Node installation iso from one of our release streams(see below)
  2. Install oVirt Node on your bare-metal host

    For manual partitioning, check (Minimum partitioning requirements session)

  3. Navigate to Cockpit on https://yourhost.example.com:9090/ to configure your host (i.e. configure networking)
  4. Navigate to Engine and add the host OR run hosted-engine-setup

If you encounter problems, please file them in bugzilla.

Releases and Streams

oVirt Node is released continously.

Usually you install Node once, using one of our installer images (see below). Afterwards you use yum update (or updates through Engine from 4.0 on) to keep your hosts updated.

Note: yum update will not update individual packages like on normal Fedora or CentOS systems, it will rather update the whole image.

Note: You can verify the integrity of any downloaded installation iso by checking the embedded checksum: checkisomd5 $ISONAME

Legacy vs. Vintage

With oVirt 4.0 Node got a complete overhaul and reimplementation - which are using Anaconda and Cockpit as described above.

Up to oVirt 3.x Node was using a custom installer, a custom administration TUI, and a custom build process. All of these - including other design decisions - caused a couple of issues, which we addressed with the re-designed oVirt Node 4.0.

oVirt Node 3

  • oVirt Node 3 Next (Tech-Preview, downwards compatible within oVirt 3, recommended)
    • This is the oVirt Node Next image, with the newly designed oVirt Node, but using the stable oVirt 3 packages.
    • Installation ISO
