How To Install virt-who on CentOS 8
virt-who is Agent for reporting virtual guest IDs to subscription-manager
Introduction
In this tutorial we learn how to install virt-who on CentOS 8.
What is virt-who
Agent that collects information about virtual guests present in the system and report them to the subscription manager.
We can use yum or dnf to install virt-who on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install virt-who.
Install virt-who on CentOS 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
The output should look something like this:
