22.5. Managing Virtual Machines

SUSE Linux Documentation Chapter 22. Virtualization / 22.5. Managing Virtual Machines
	22.4. Starting the Virtualization Host Server		22.6. Creating Virtual Machines

Virtual machines can be created and managed by using the Virtual Machine Manager.

On the virtualization host server, click YaST+Virtualization+Virtual Machine Manager.
The Virtual Machine Manager page displays the virtualization host server (Domain-0) and all virtual machines.
From the Virtual Machine Manager page, you can perform the following actions:
- New starts the process to create a new virtual machine.
- Details displays status and hardware of the selected virtual machine or Domain-0
- Open displays the command console for the selected virtual machine.
- Delete completely removes the selected virtual machine.
- Start a virtual machine by selecting it from the list, click Open, and then click Run.

Virtual Machine Manager is recommended for managing virtual machines, but you can also perform actions by entering commands on the command line.
