第 5 章 Starting virtual machines

Prerequisites

• 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.
• If you want to start a VM that uses the system connection of libvirt, you must have root privileges or be in the libvirt user group on the host. For more information, see User-space connection types for virtualization.

Procedure

• 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 192.0.2.1 host.

  # virsh -c qemu+ssh://root@192.0.2.1/system start demo-guest1
  
  root@192.0.2.1's password:
  
  Domain 'demo-guest1' started
