How to map a serial port to the guest virtual machine with UTM?

Question

I'm running a Debian VM on MacOS with an Apple Silicon chip using UTM, and I can't figure out how to map the serial port to my VM so that it can use the serial port.

I already tried to add -serial /dev/tty.usbserial-0001 to the QEMU command but it makes QEMU crash.

With UTM I get this error during the launch :

QEMU error: QEMU exited from an error : qemu-aarch64-softmmu: -serial /dev/tty.usbserial-0001: could not connect serial device to character backend '/dev/tty.usbserial-0001'

If I try with a mere QEMU command the VM freeze at the very start of the launch with a endless spinning cursor :

qemu-system-aarch64 -M virt -accel hvf -cpu host -m 8G -drive file=ubuntu.raw,format=raw -bios /opt/homebrew/share/qemu/edk2-aarch64-code.fd -device virtio-gpu-pci -device qemu-xhci -device usb-kbd -device usb-mouse -device virtio-sound-pci -serial /dev/tty.usbserial-0001 -cdrom /Users/user/Downloads/noble-desktop-arm64.iso

Does anyone know how to do this? I can't use VirtualBox because it doesn't run on the new Macs.

Additionally, if someone has a solution using QEMU directly, that would be helpful too, since UTM is essentially a wrapper for QEMU.

Thx!
