29.1. Overview of virtual machine management by 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.

29.2. Setting up the web console to manage virtual machines

Before using the RHEL 9 web console to manage virtual machines (VMs), you must install the web console virtual machine plug-in on the host.

Prerequisites

  • Ensure that the web console is installed and enabled on your machine.

    # systemctl status cockpit.socket
    cockpit.socket - Cockpit Web Service Socket
    Loaded: loaded (/usr/lib/systemd/system/cockpit.socket
    [...]

    If this command returns Unit cockpit.socket could not be found, follow the Installing the web console document to enable the web console.

Procedure

  • Install the cockpit-machines plug-in.

    # dnf install cockpit-machines

Verification

  1. Access the web console, for example by entering the https://localhost:9090 address in your browser.
  2. Log in.
  3. If the installation was successful, Virtual Machines appears in the web console side menu.

29.3. Renaming virtual machines by using the web console

You might require renaming an existing virtual machine (VM) to avoid naming conflicts or assign a new unique name based on your use case. To rename the VM, you can use the RHEL web console.

Prerequisites

Procedure

  1. In the Virtual Machines interface, click the Menu button of the VM that you want to rename.

    A drop-down menu appears with controls for various VM operations.

  2. Click Rename.

    The Rename a VM dialog appears.
