People would begin to depend on this, and any change in this behaviour would be a breaking bug, and would introduce implicit stability contracts for complex scenarios. And some way to test this, and test this automatically, so that this stuff doesn't immediately rot away. It would have to be aware of different operating systems, operating system image formats for autodetection, OS releases and their corresponding quirks. That would add a ton of new responsibility to a codebase that so far has been doing none of this. > But it would be easy to design qemu to have 1000+ config options which are on/off/auto settings, and the 'auto' mode is autodetected based on which OS is probably running. Option (2) only works on Apple hardware, and so by using option (2) Apple's license condition, of only virtualising macOS on Apple hardware, is automatically enforced.Ĭonsidering that VirtualBox is from Oracle, and as well as open source, they also sell it as a commercial product, you can understand why Oracle's lawyers want option (2). Option (2) is a lot of extra complexity compared to option (1), but has the advantage of being legally much cleaner.

VirtualBox already has a bunch of kexts needed to provide various features, and so this is just a bit more code in one of those kexts. Apple doesn't supply a public API to retrieve this value, so VirtualBox has some code which runs inside a macOS kernel extension, and directly uses the SMC hardware registers to request it. Obviously method (2) only works if your host is a Mac. When enabled, VirtualBox retrieves the value from the SMC of your Mac. (2) Ensure the 'GetKeyFromRealSMC' boolean config parameter is enabled (not sure if it is turned on by default or not). (1) You supply this value in the 'DeviceKey' config parameter VirtualBox supports two methods of operation:
