+1 for this feature!

Not sure if needed but below a script that I created (with help of google) that uses fog to clone a vm with almost everything that I need or like to have.

I'm still trying to find a way to change the disk sizes of the newly created vm.

I assume it might be possible to change the "New Host" UI and feed the network, cpu, mem and location choices based on a selected template or vm and use a vm_clone fog command instead of an vm_create command with foreman.

#!/usr/bin/env ruby

require 'fog'
require 'pp'

connection = Fog::Compute[:vsphere]
puts "Connected to #{connection.vsphere_server} as #{connection.vsphere_username} (API version #{connection.vsphere_rev})"

options = {
'datacenter' => 'CJIB',
'template_path' => '/rhel6_clone',
'name' => 'rhel6_vm',
'power_on' => true,
'memoryMB' => '1024',
'network_label' => 'dvportgroup-255',
'network_adapter_device_key' => '4000',
'numCPUs' => 2,
'resource_pool' => ['thuis','resource pool 2'],
'datastore' => 'datastore1',
'dest_folder' => 'RHEL/Servers',
'wait' => true,

}

new_vm=connection.vm_clone(options)
pp new_vm

I'm also thinking of trying to do this with foreman hooks but not yet sure if that will produce the desired result.
