clonevm.1

NAME

clonevm - Create masters from virtual machines and virtual machines from masters.

SYNOPSIS

clonevm noderange [ -t master_to_be_made | -b master_to_base_vms_upon ] [ -d|--detached] [-f|--force]

DESCRIPTION

Command to promote a VM’s current configuration and storage to a master as well as performing the converse operation of creating VMs based on a master.

By default, attempting to create a master from a running VM will produce an error. The --force argument will request that a master be made of the VM anyway.

Also, by default a VM that is used to create a master will be rebased as a thin clone of that master. If the --force argument is used to create a master of a powered on vm, this will not be done. Additionally, the --detached option can be used to explicitly request that a clone not be tethered to a master image, allowing the clones to not be tied to the health of a master, at the cost of additional storage.

When promoting a VM’s current state to master, all related virtual disks will be copied and merged with any prerequisite images. A master will not be tethered to other masters.
