KVM, QEMU, and Libvirt are virtualization technologies considered for Vagrant on Apple Silicon M4.KVM is not supported on macOS and Apple Silicon does not allow KVM passthrough even via emulation layers.Libvirt adds complexity on macOS and requires running a Linux VM to use it with QEMU.QEMU is the recommended option for Apple M4, as it is native to macOS, supports ARM64 architecture, and integrates well with Vagrant.
