bhyve does not run NetBSD-i386 cd

[Sergio de Almeida Lenzi]

Hello

I am trying to run/install a Bhyve vm for NetBSD-i386 any version but the bhyve aborts with a signal trap error.
Interesting note that iso from AMD64 runs fine

Steps to reproduce the error
1) download NetBSD iso => https://cdn.netbsd.org/pub/NetBSD/NetBSD-9.0/images/NetBSD-9.0-i386.iso
2) install vm-bhyve port => sysutils/vm-bhyve
3) create and install vm 
	vm init
	vm create -t netbsd -s 20G -m 1024M NetBSD
	vm install  -f NetBSD NetBSD-9.0.i386.iso   => abort trap
the system opens a terminal, shows grub prompt on start the machine, it aborts with the message "Abort Trap"
This happens on every version of FreeBSD(amd64)  including FreeBSD 13.0-CURRENT #0 r357847M

Thank you for any help
