![]() ![]() We also got the SPARC version of Sun Solaris 9 running on both machines, too. ![]() If you don't want to configure your own VM, UTM offers a gallery of pre-built guest images, and in testing, we've successfully run the PowerPC-native Classic MacOS 9.2.1 on both M1 and Core i7 Macs. It can use the Apple hypervisor directly, virtualizing your underlying Intel or Apple Silicon CPU, but as well as that, it can also use QEMU, either as a hypervisor for native-speed virtualization, but also, in emulation mode. UTM wraps a friendly GUI around two different hypervisors, one of them able to run in two different modes. It can work both as a full-system emulator and as a type 2 hypervisor with the help of a kernel and CPU that provide the relevant functionality. This is where the misunderstanding of QEMU comes from. Rather less well known is that it can do the same on macOS. In this mode, QEMU does no processor emulation at all: the OS is providing that, meaning that the guest code runs at close to native speed on the real underlying CPU. Essentially, the Linux kernel provides the CPU, and QEMU does the rest. It's widely used in most Linux distros to provide this supplementary front-end scaffolding: to create, provide and manage all the additional hardware for VMs. ![]()
