29# -machine virt specifies a type of a machine - we have no interest in emulating a specific hardware so we just use the special type virt
30# the accel=hvf part is the important one: it enables hardware acceleration using macOS Hypervisor Framework
31# -cpu host specifies that the guest machine will see exactly the same CPU model as the host machine (required for acceleration)
