Parallels Desktop allows you to connect or disconnect certain devices at runtime or switch some of them to use other media. Generally, the following virtual devices can be connected or disconnected at runtime:
Removable media drives
Network adapters
Sound devices
USB devices
Shared folders
If parallel and serial ports are present in the virtual machine configuration, you can also manage them on the go. To configure any of these devices, use the necessary command from the Devices menu in the menu bar. This menu is available only when the virtual machine is running.
If you have several CD/DVD drives connected to your virtual machine, in the Devices menu they are listed in the same order as they were connected. The first CD/DVD drive will be CD/DVD 1, the second will be CD/DVD 2, and so on.
You can set up any of the three network modes: Shared Networking, Bridged Networking, or Host-Only Networking.
To connect or disconnect a sound device, choose the type of output (or input) device or Mute option respectively.
Parallels Desktop automatically detects all USB devices plugged into your Mac computer. The devices that are currently connected to the virtual machine appear in the list from the Device menu. You cannot use a USB device in macOS while it is being used by the virtual machine.
The Shared Folders options available at runtime are similar to the settings in the Virtual Machine Configuration dialog.
You can:
share all Mac disks or Home Folder only with the virtual machine;
share Windows guest operating system disks with macOS;
add a new shared folder.
To connect or disconnect a serial port, click the Devices menu, select the corresponding serial port, and choose the appropriate command in the displayed menu.
To connect to a printer or an output file, click the Devices > Printer menu, select your preferred printer, or choose to print to a file.
