Virtual Machine Pool XMLElements are missing USER_TEMPLATE

[dann1]

Description When iterating a VirtualMachinePool object to get all of the vms as XMLElements, the vms are missing the USER_TEMPLATE section.

The code in question is

vm_pool = VirtualMachinePool.new(client)
rc      = vm_pool.info_all

raise rc.message if OpenNebula.is_error?(rc)

vms = vm_pool.retrieve_xmlelements('/VM_POOL/VM')

The vms array will contain vm XML elements without USER_TEMPLATE

To Reproduce

Use the following ruby code as an example

require 'opennebula'
include OpenNebula

CREDENTIALS = ''# your credentials here
ENDPOINT = ''#oned wherever it is running
client = Client.new(CREDENTIALS, ENDPOINT)

vm_pool = VirtualMachinePool.new(client)
rc      = vm_pool.info_all

raise rc.message if OpenNebula.is_error?(rc)

vms = vm_pool.retrieve_xmlelements('/VM_POOL/VM')

vms.each do |vm|
    puts '---------'
    puts vm['ID']
    puts '---------'
    puts vm['USER_TEMPLATE']
    puts '---------'

    vm = VirtualMachine.new_with_id(vm['ID'], client)
    rc = vm.info
    raise rc.message if OpenNebula.is_error?(rc)

    puts '=========='
    puts vm['ID']
    puts '=========='
    puts vm['USER_TEMPLATE']
    puts '=========='
end

And it will output

The difference content wise is clear. Although it looks like SCHED_REQUIREMENTS and SCHED_DS are correctly loaded. However, everything else is missing.

Expected behavior The second part of the loop in the code where the VM is loaded individually by its ID works as expected

    vm = VirtualMachine.new_with_id(vm['ID'], client)
    rc = vm.info
    raise rc.message if OpenNebula.is_error?(rc)

Additional context Even using the user_template_str method yields nil on the vm from the vm_pool yields nil.
