For increased security, you can add a virtual cryptoprocessor that is equipped with Trusted Platform Module (TPM) technology to an encrypted virtual machine.



  1. Select the virtual machine and select VM > Settings.
  2. Click Add.
  3. Click Trusted Platform Module.
    If the option is not available, the Trusted Platform Module device is not supported on the guest.
  4. Click Finish.
  5. Click OK.


The virtual machine uses the virtual TPM device.
Note: When a TPM device is present on a virtual machine, you cannot perform the following actions.
  • Decrypt the virtual machine.
  • Change the firmware type to BIOS.
