My env.
windows10 host, and using QEMU aarch64 system emulation,
QEMU is executed under cygwin-terminal

Release 13.0 was booted and can enter single user mode ,but could not enter multi-user mode. QEMU is quit.

startup script:
# for freebsd arm
imgfile='.\\FreeBSD-13.0-RELEASE-arm64-aarch64.qcow2'
#imgfile='.\\FreeBSD-12.2-RELEASE-arm64-aarch64.qcow2'
fmt=qcow2
biosf='.\\QEMU_EFI.fd'
#biosf=edk2-aarch64-code.fd

$qemusys \
        -m 4096M -cpu cortex-a72 -M virt,highmem=off -k ja -smp 2 \
        -bios $biosf \
        -drive if=none,file=$imgfile,format=$fmt,id=hd0 \
        -device virtio-blk-device,drive=hd0 \
        -device qemu-xhci \
        -device usb-kbd \
        -netdev tap,id=net0,ifname=$tap -net nic,macaddr=$mymac,netdev=net0 \
        -serial mon:stdio \
        -nographic \

---------------
Under single user mode, there is no ttyv(0...) virtual terminal device file.
During boot sequence to multi-user mode, following cons message found,
...
Starting devd.
eval: cannot open /dev/ttyv0: No such file or directory
eval: cannot open /dev/ttyv0: No such file or directory
Starting dhclient.
...

I think due to lack of ttyv? device file, init could not open virtual terminal by getty.

Is there any workaround?
