2.5. Cloning Virtual Machines and Containers

You can create a copy (clone) of a particular virtual machine or container that will have identical data and resource parameters. Cloning may save time as clones require little reconfiguration compared to setting up new virtual machines or containers.

You can clone both stopped and running virtual machines and containers. For example:

# prlctl clone MyCT --name MyCT_clone
# prlctl clone MyVM --name MyVM_clone

The --name option specifies a name for the clone.

When cloning Windows virtual machines, consider changing their security identifiers (SIDs) with the --changesid option.

Successfully cloned virtual machines and containers will be shown in the list of virtual environments on the host. For example:

# prlctl list -a
UUID            STATUS       IP_ADDR          T  NAME
{62951c2a-...}  stopped      10.30.10.101     CT MyCT
{49b66605-...}  stopped      10.30.10.101     CT MyCT_clone
{7f4904ad-...}  stopped      10.30.128.115    VM MyVM
{2afb2aa2-...}  stopped      10.30.128.134    VM MyVM_clone

The example above shows that the cloned container has the same IP address as the original container. Before starting to use the clones, make sure their IP addresses are unique (for instructions on how to assign IP addresses to VMs and containers, see Section 2.2.3, “Configuring Network Settings”).
