 | template_version   | UNDEF                 | Version number of the template to be used for VM. By default the latest available version of the template is used.   |
+| boot_disk_name     | UNDEF                 | Renames the bootable disk after the VM is created. Useful when creating VMs from templates |
+| boot_disk_use_vm_name_prefix | true        | Use the name of the virtual machine as prefix when renaming the VM boot disk. The resulting boot disk name would be <i>{{vm_name}}_{{boot_disk_name}}</i>|
+| boot_disk_size     | UNDEF                 | Resizes the bootable disk after the VM is created. A suffix that complies to the IEC 60027-2 standard (for example 10GiB, 1024MiB) can be used. |

 | memory_guaranteed  | UNDEF                 | Amount of minimal guaranteed memory of the Virtual Machine. Prefix uses IEC 60027-2 standard (for example 1GiB, 1024MiB). <i>memory_guaranteed</i> parameter can't be lower than <i>memory</i> parameter. |
