Chapter 8. Managing virtual machines in the web console
To manage virtual machines in a graphical interface on a RHEL 9 host, you can use the Virtual Machines pane in the RHEL 9 web console.
8.1. Overview of virtual machine management using the web console
The RHEL 9 web console is a web-based interface for system administration. As one of its features, the web console provides a graphical view of virtual machines (VMs) on the host system, and makes it possible to create, access, and configure these VMs.
Note that to use the web console to manage your VMs on RHEL 9, you must first install a web console plug-in for virtualization.
