Step 7: Choose the operating systemDeciding which operating system should run on the virtual machine is important. For current server operating systems, this will set important options such as 64-bit execution mode. Windows Server 2008 R2 is available only in x64, so selecting the correct operating system will ensure the optimal performance of the virtual machine from the base configuration. This starts with the virtual machine BIOS that is assigned to each virtual machine. vSphere supports a number of new operating systems, including DOS, SCO OpenServer, SCO UnixWare, OS/2, FreeBSD, Windows 3.1 and others.
