limactl start --vm-type=qemu fails with {"level":"debug","msg":"qemu[stderr]: qemu-system-aarch64: Property 'host-arm-cpu.sme' not found","time":"2024-12-18T12:34:14+09:00"} in ha.stderr.log.

  • Host: macOS 15.2, on MacBook Pro 2024 (M4 Max)
  • Lima: v1.0.2
  • QEMU: v9.2.0

Similar issues:

This issue seems specific to Apple M4 (introduced SME) and macOS 15.2

Workaround

limactl edit --set '.cpuType.aarch64="cortex-a57"' INSTANCE
