Are you trying to add Compute Host to oVirt Virtualization?

This guide will help you.

You can add 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.

Here at Ibmi Media, as part of our Server Management Services, we regularly help our Customers to perform Virtualization related queries.

In this context, we shall look into how to add Compute Host to oVirt Virtualization.

More information about oVirt Virtualization ?

oVirt is an open-source distributed virtualization solution. It is mainly designed to manage the entire enterprise infrastructure. Also, it uses a trusted KVM hypervisor. Moreover, it is built upon several other community projects, including libvirt, Gluster, PatternFly, and Ansible.

One can install oVirt Engine using either the Dedicated instance or using the Hosted Engine.

Here, you will see how to add compute hosts to oVirt for Virtual Machines to be provisioned using the oVirt Engine administration dashboard.

How to add Compute Host to oVirt Virtualization?

Follow the steps below to add the compute host.

1. CentOS 8 Server preparation

First, add all the required packages for CentOS 8 Physical Servers:

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

Next, enable Cockpit service:

$ sudo systemctl enable –now libvirtd cockpit.socket

Now add Compute Host to oVirt.

Here are the steps for it.

i. First, log in to the console and validate oVirt Engine installation.

ii. Next, navigate to Compute > Hosts > New and fill in all required information.

iii. In the left panel, modify other settings and click "OK" button to provision the node.

iv. Finally, the Status should change to Installing and will finish in a few minutes.

2. Configure Host Networking

In case, if you wish to add any additional networks – extra bridges with VLANs, etc, this can be done once the host is added.

i. Firstly, create a Logical Network on Network > New. Then give Virtual Network correct details. For VLAN ID check "Enable VLAN tagging".

ii. After adding the Host activating it, you can configure its networking under Network Interfaces > Setup Host Networks.

iii. Then assign the Logical network to an interface.

iv. Drag Virtual Network for mapping to host interface.

v. Also, configure IP addressing if necessary.

vi. After saving and returns as successful, it should turn green.

vii. Finally, you can proceed to create virtual machines using oVirt Management interface.
