Sorry, missed that one.

builder = "hvm"
name = "FreeBSD"
disk = [
        '/dev/zvol/zroot/freebsd1,raw,hda,w',
        '/dev/zvol/zroot/freebsd2,raw,hdb,w',
        '/dev/zvol/zroot/builder0,raw,hdc,w',
        '/dev/zvol/zroot/builder1,raw,hdd,w'
]
boot = "c"
usbdevice = 'tablet'
#nographics = 1
#serial = [ "/dev/nmdm0A" ]
vnc = 1
#vnclisten = '0.0.0.0'
vif = ['bridge=bridge0,mac=00:02:04:08:fd:f0']
memory=4096
vcpus=4
vga = "stdvga"
videoram = 16
xen_platform_pci=0

/boot/loader.conf is

loader_logo=none
beastie_disable=yes

Looks like

xen_platform_pci=0

was a culprit (something I need to boot Fedora)
