Chapter 8. Shutting down and restarting virtual machines

Shutting down a responsive VM

• If you are connected to the guest, use a shutdown command or a GUI element appropriate to the guest operating system.

  Note

  In some environments, such as in Linux guests that use the GNOME Desktop, using the GUI power button for suspending or hibernating the guest might instead shut down the VM.

• Alternatively, use the virsh shutdown command on the host:

  • If the VM is on a local host:

    # virsh shutdown demo-guest1
    Domain 'demo-guest1' is being shutdown

    Copy to Clipboard Toggle word wrap

  • If the VM is on a remote host, in this example 192.0.2.1:

    # virsh -c qemu+ssh://root@192.0.2.1/system shutdown demo-guest1
    
    root@192.0.2.1's password:
    Domain 'demo-guest1' is being shutdown

    Copy to Clipboard Toggle word wrap

Verification

• On the host, display the list of your VMs to see their status.

  # virsh list --all
  
   Id    Name                 State
  ------------------------------------------
   1     demo-guest1          shut off

  Copy to Clipboard Toggle word wrap

Prerequisites

• You have installed the RHEL 10 web console.

  For instructions, see Installing and enabling the web console.

• The web console VM plugin is installed on your system.

Troubleshooting

• If the VM does not shut down, click the Menu button ⋮ next to the Shut Down button and select Force Shut Down.
• To shut down an unresponsive VM, you can also send a non-maskable interrupt by clicking the Send non-maskable interrupt button in the Menu.

Restarting a responsive VM

• If you are connected to the guest, use a restart command or a GUI element appropriate to the guest operating system.

• Alternatively, use the virsh reboot command on the host:

  • If the VM is on a local host:

    # virsh reboot demo-guest1
    Domain 'demo-guest1' is being rebooted

    Copy to Clipboard Toggle word wrap

  • If the VM is on a remote host, in this example 192.0.2.1:

    # virsh -c qemu+ssh://root@192.0.2.1/system reboot demo-guest1
    
    root@192.0.2.1's password:
    Domain 'demo-guest1' is being rebooted

    Copy to Clipboard Toggle word wrap

Verification

• On the host, display the list of your VMs to see their status.

  # virsh list --all
  
   Id    Name                 State
  ------------------------------------------
   1     demo-guest1          running

  Copy to Clipboard Toggle word wrap

Prerequisites

• You have installed the RHEL 10 web console.

  For instructions, see Installing and enabling the web console.

• The web console VM plugin is installed on your system.

Troubleshooting

• If the VM does not restart, click the Menu button ⋮ next to the Reboot button and select Force Reboot.
• To shut down an unresponsive VM, you can also send a non-maskable interrupt by clicking the Send non-maskable interrupt button in the Menu.
