clonevm.1

NAME

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

SYNOPSIS

clonevm noderange [ -t mastertobemade | -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 rleated virtual disks will be copied and merged with any prerequisite images. A master will not be tethered to other masters.

OPTIONS

-h|--help Display usage message.

-b The master to base the clones upon

-t The target master to copy a single VM’s state to

-d Explicitly request that the noderange be untethered from any masters.

-f Force cloning of a powered on VM. Implies -d if the VM is on.

-v|--version Command Version.

-V|--verbose Verbose output.

RETURN VALUE

0: The command completed successfully.

Any other value: An error has occurred.

EXAMPLES

  1. Creating a master named appserver from a node called vm1:
