# Adding/Modifying a Device

The general syntax for adding a device is as follows:

**prlctl set** <*vm\_id* | *vm\_name*> **--device-add** <**hdd** | **cdrom** | **net** | **fdd** | **serial** | **parallel** | **sound** | **usb**> \[*device\_options*]

To modify a device:

**prlctl set** <*vm\_id* | *vm\_name*> **--device-set** <*device\_name*> \[*device\_options*]

The subsequent sections describe options and parameters for each device type.

To delete a device:

**prlctl set** <*vm\_id* | *vm\_name*> **--device-del** <**hdd** | **cdrom** | **net** | **fdd** | **serial** | **parallel** | **sound** | **usb**> \[*device\_options*]
