Our recent articles covered installation of oVirt Engine using the two standard methods – Dedicated instance and using Hosted Engine. In this blog post we will dive into addition of compute hosts to oVirt for Virtual Machines to be provisioned using oVirt Engine administration dashboard. Compute hosts servers can be Enterprise Linux Server such as CentOS 8 or oVirt Node server.

If using oVirt Nodes, download the ISO files and use it to install the operating system into the physical hardware.

install ovrt node 01

CentOS 8 Server preparation

For CentOS 8 Physical Servers add the oVirt YUM repository which contains all the packages required.

sudo dnf -y install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm

Enable Cockpit service.

sudo systemctl enable --now libvirtd cockpit.socket

Add Compute Host to oVirt

Validate oVirt Engine installation by logging into the console.

install ovirt centos 01

Navigate to Compute > Hosts > New and fill all required information.

add compute host ovirt 001

Modify other settings in the left panel as you see fit and click “OK” button to provision the node.

add compute host ovirt 002

The Status should change to Installing and will finish in few minutes.

add compute host ovirt 003

Configure Host Networking

If you want to add additional networks – extra bridges with VLANs e.t.c, this can be done once the host is added.

First create a Logical Network on Network > New. Give Virtual Network correct details. For VLAN ID check “Enable VLAN tagging

add compute host ovirt 006

With the Host added and active you can configure its networking under Network Interfaces > Setup Host Networks:

add compute host ovirt 004

Assign the Logical network to an interface.

add compute host ovirt 005

Drag Virtual Network for mapping to host interface.

add compute host ovirt 007

Configure IP addressing if required.

add compute host ovirt 008

Once saved and successful it should turn green.

add compute host ovirt 009

You can then proceed to create virtual machines using oVirt Management interface. Refer to below guides:
