More about oVirt Guest Agent ?

The oVirt/Red Hat Virtualization guest agent provides information, notifications, and actions between the oVirt web interface and the guest.

The agent provides the Machine Name, Operating System, IP Addresses, Installed Applications, Network, and RAM usage among other Virtual Machine information to the web interface.

The agent also provides Single Sign-On so an authenticated user to the web interface does not need to authenticate again when connected to a VM.

On CentOS 7/RHEL 7, the package to install is called ovirt-guest-agent. However, in CentOS 8/RHEL 8, the package we install is referred to by the name qemu-guest-agent.


Now let us proceed with the installation oVirt Guest Agent on CentOS 8 and RHEL 8.


How to Install oVirt Guest Agent on CentOS 8 ?

On CentOS 8, we execute the command:

sudo yum -y install qemu-guest-agent

Initially, we install and enable the service:

sudo systemctl enable –now qemu-guest-agent

Then we check service status to ensure it is running:

$ systemctl status qemu-guest-agent

How to Install oVirt Guest Agent on RHEL 8 ?

For an RHEL 8 machine, we have to enable the Red Hat Virtualization Agent repository:

sudo subscription-manager repos –enable=rhel-8-for-x86_64-appstream-rpms

Once done, install the package:

sudo yum -y install qemu-guest-agent

Then we ensure the service is running:

sudo systemctl start qemu-guest-agent
sudo systemctl enable qemu-guest-agent

Finally, we check the status:

$ systemctl status qemu-guest-agent

The web admin interface may take some time to display the memory usage and other types of information. If the information does not populate, restart the VM and verify that the service is running.
