Can I install oVirt Guest Agent on CentOS 8 / RHEL 8 Linux guest?. 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.
On CentOS 7 / RHEL 7, the package to be installed is called ovirt-guest-agent. This has changed in CentOS 8 / RHEL 8, as it is referred by the name qemu-guest-agent . So how can you install oVirt Guest Agent and Drivers on CentOS 8 / RHEL 8?.

For a RHEL 8 machine, you’re required to enable the Red Hat Virtualization Agent repository:
sudo subscription-manager repos --enable=rhel-8-for-x86_64-appstream-rpmsOnce this is done, install the package:
sudo yum -y install qemu-guest-agentEnsure the service is started and running:
sudo systemctl start qemu-guest-agent
sudo systemctl enable qemu-guest-agentCheck the status:
systemctl status qemu-guest-agentFor CentOS 7 and Debian/Ubuntu, check: installing ovirt guest agent on Linux
Hey,
I followed your tutorial but when I run sudo systemctl start qemu-guest-agent I get this error:
A dependency job for qemu-guest-agent.service failed. See ‘journalctl -xe’ for details.
and journalctl shows the following:
Guest agent is not responding: QEMU guest agent is not connected
dev-virtio\x2dports-org.qemu.guest_agent.0.device: Job dev-virtio\x2dports-org.qemu.guest_agent.0.device/start timed out.
Timed out waiting for device dev-virtio\x2dports-org.qemu.guest_agent.0.device.
Unit dev-virtio\x2dports-org.qemu.guest_agent.0.device has failed
And sudo systemctl enable qemu-guest-agent gives me this error:
Unit /usr/lib/systemd/system/qemu-guest-agent.service is added as a dependency to a non-existent unit dev-virtio\x2dports-org.qemu.guest_agent.0.device.
How can I solve this?
Thank you in advance.
We’ve noted the same in our test. It must be a new bug. We’ll try see if solution is there.
