Next step I tried with an ISO image:

Code:
-cdrom FreeBSD-12.0-RELEASE-amd64.qcow2

You're trying to load a Qcow disk image as a CD-ROM.

Read the instructions again, you're not following them. Qcow is a disk image, not a CD image. You're supposed to load it as the hard disk. It's not an installer, it's an already installed disk image.

could you please help to understand why this formula is not working ?

and it stay halted
 
just to make something clear in case you did not know it: qemu does not use your cpus feature for hardware virtualization under FreeBSD. If you want hardware virtualization, use bhyve or virtualbox. and btw: kvm is Linux technology for virtualization
