To manage virtual machines in a graphical interface, you can use the Virtual Machines pane in the the web console.

web console overview

The following sections describe the web console’s virtualization management capabilities and provide instructions for using them.

9.1. Overview of virtual machine management using the the web console

The the web console is a web-based interface for system administration. With the installation of a web console plug-in, the web console can be used to manage virtual machines (VMs) on the servers to which the web console can connect. It provides a graphical view of VMs on a host system to which the web console can connect, and allows monitoring system resources and adjusting configuration with ease.

Using the the web console for VM management, you can do the following:

  • Create and delete VMs
  • Install operating systems on VMs
  • Run and shut down VMs
  • View information about VMs
  • Create and attach disks to VMs
  • Configure virtual CPU settings for VMs
  • Manage virtual network interfaces
  • Interact with VMs using VM consoles

9.2. Setting up the the web console to manage virtual machines

Before using the the web console to manage VMs, you must install the web console virtual machine plug-in.

Prerequisites

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

    $ yum info cockpit
    Installed Packages
    Name         : cockpit
    [...]

Procedure

  • Install the cockpit-machines plug-in.

    # yum install cockpit-machines

    If the installation is successful, Virtual Machines appears in the web console side menu.
