The guest operating system that you specify affects the supported devices and available number of virtual CPUs. You specify the guest operating system in the following two properties:
- guestosid – Specify one of the constants in the VirtualMachineGuestOsIdentifier as a string.
- alternateGuestName – Full name for the guest operating system. Use this property if guestosid is one of the values of VirtualMachineGuestOsIdentifier starting with other*.
