Hi,
I have one VM with FreeBSD-11.2-RELEASE-amd64.qcow2 image and it works
fine under qemu 2.12.1. But it's controlled by libvirt + virt-manager,
so it has a bit more cmdline arguments than in wiki.

In general, those images has serial console disabled by default.

Creating the following file in VM fs:
[root@freebsd ~]# cat /boot/loader.conf 
boot_multicons="YES"
boot_serial="YES"
comconsole_speed="115200"
console="comconsole,vidconsole"

allows me to successfully boot with:
# qemu-system-x86_64 -machine accel=kvm -m 2048  \
      -cpu host -enable-kvm -nographic -smp 2 \
      -drive if=virtio,file=./FreeBSD-11.2-RELEASE-amd64.qcow2,format=qcow2

Best regards, Ilya Maximets.
