A guest operating system is the system that runs in a virtual machine. Fusion supports importing Parallels and Virtual PC virtual machines with certain operating systems.

Fusion supports importing the following operating systems:

  • Microsoft Windows 10

  • Microsoft Windows 8

  • Microsoft Windows 7

  • Microsoft Windows Vista

  • Microsoft Windows XP Service Pack 3

  • Microsoft Windows XP Service Pack 2

Virtual machines must be powered off before you import them.

If your copy of Windows was not licensed with a volume-license key, you might need to reactivate it when it starts inside Fusion.
