All of the options listed below are optional, and thus the default value specified will be used when the corresponding key-value pair is not specified.

• Key: enabled

  Value: 0 or 1

  Default: 0

• Key: vendor

  Value: Hyper-V vendor signature reported by CPUID to the guest

  Default: When debugging is enabled: Microsoft Hv, otherwise: VBoxVBoxVBox

  Value: 0 or 1

  Default: 0

• Key: vsinterface

  Value: 0 or 1
