Use the new userboot 'getenv' callback to set a couple of environment variables
in the guest. The variables are: smbios.bios.vendor=BHYVE and boot_serial=1 The FreeBSD guest uses the "smbios.bios.vendor" environment variable to detect whether or not it is running as a guest inside a hypervisor. The "boot_serial=1" is temporary and will be dropped when bhyve can do VGA emulation. Obtained from: NetApp
