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

VMware Fusion supports importing the following operating systems:

Microsoft Windows 8

Microsoft Windows 7

Microsoft Windows Vista

Microsoft Windows Server 2008

Microsoft Windows Server 2003

Microsoft Windows XP Service Pack 3

Microsoft Windows XP Service Pack 2

Microsoft Windows 2000 Service Pack 4

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 is booted up inside VMware Fusion.
