Chapitre 4. Starting virtual machines

To start a virtual machine (VM) in RHEL 9, you can use the command line interface or the web console GUI.

Conditions préalables

  • Before a VM can be started, it must be created and, ideally, also installed with an OS. For instruction to do so, see Creating virtual machines.

4.1. Starting a virtual machine using the command-line interface

You can use the command line interface (CLI) to start a shut-down virtual machine (VM) or restore a saved VM. Using the CLI, you can start both local and remote VMs.

Conditions préalables

  • An inactive VM that is already defined.
  • The name of the VM.

  • For remote VMs:

    • The IP address of the host where the VM is located.
    • Root access privileges to the host.

Procédure

  • For a local VM, use the virsh start utility.

    For example, the following command starts the demo-guest1 VM. 

    # virsh start demo-guest1
Domain 'demo-guest1' started

  • For a VM located on a remote host, use the virsh start utility along with the QEMU+SSH connection to the host.

    For example, the following command starts the demo-guest1 VM on the 192.168.123.123 host. 

    # virsh -c qemu+ssh://root@192.168.123.123/system start demo-guest1

root@192.168.123.123's password:

Domain 'demo-guest1' started
