4.2. Cloning a Virtual Machine
Before proceeding with cloning, shut down the virtual machine. You can clone the virtual machine using
virt-clone or virt-manager.
4.2.1. Cloning Guests with virt-clone
You can use

The
virt-clone man page also documents each command option, important variables, and examples.
The following example shows how to clone a guest virtual machine called "demo" on the default connection, automatically generating a new name and disk clone path.
Example 4.1. Using virt-clone to clone a guest
# virt-clone --original demo --auto-clone
The following example shows how to clone a QEMU guest virtual machine called "demo" with multiple disks.
Example 4.2. Using virt-clone to clone a guest
# virt-clone --connect qemu:///system --original demo --name newdemo --file /var/lib/libvirt/images/newdemo.img --file /var/lib/libvirt/images/newdata.img4.2.2. Cloning Guests with virt-manager
This procedure describes cloning a guest virtual machine using the virt-manager utility.
Procedure 4.2. Cloning a Virtual Machine with virt-manager
Open virt-manager
Start virt-manager. Launch the application from the menu and submenu. Alternatively, run thevirt-managercommand as root.Select the guest virtual machine you want to clone from the list of guest virtual machines in Virtual Machine Manager.Right-click the guest virtual machine you want to clone and select . The Clone Virtual Machine window opens.

- For each disk in the cloned guest virtual machine, select one of the following options:
Clone this disk- The disk will be cloned for the cloned guest virtual machineShare disk with guest virtual machine name- The disk will be shared by the guest virtual machine that will be cloned and its cloneDetails- Opens the Change storage path window, which enables selecting a new path for the disk
