=head1 NAME
|
|
|
|
B<clonevm> - Create masters from virtual machines and virtual machines from masters.
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
I<clonevm noderange [ -t <mastertobemade> | -b <master to base vms upon> ] -d|--detached -f|--force>
|
|
|
|
=head1 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.
