[Bug 188990] [xen] dhclient(8) does not accept DHCP Offer on FreeBSD 10 as Xen DomU Guest

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=188990

--- Comment #33 from mario felicioni <marietto2008@gmail.com> ---
This is the script that I use when I boot the debian vm under xen :

name="debian"
kernel =
'/mnt/zroot2/zroot2/OS/Chromebook/linux-xen/domU-linux/zImage-6.1.59-stb-xen-cbe+'
memory=512
vcpus=1
autoballon="on"
disk = [ 'debian.img,raw,xvda,w' ]
vfb = [ 'type=vnc,vnclisten=0.0.0.0,vncdisplay=1' ]
vif = [ 'type=vif,mac=00:16:3e:xx:xx:xx,script=vif-route-local,ip=192.168.1.14'
]
extra = 'console=hvc0 root=/dev/xvda rw init=/sbin/init
xen-fbfront.video=24,1024,768'


This is the script that's invoked when I launch the vm :


#!/bin/bash
#============================================================================
# ${XEN_SCRIPT_DIR}/vif-route
#
# Script for configuring a vif in routed mode.
#
# Usage:
# vif-route (add|remove|online|offline)
#
# Environment vars:
# dev vif interface name (required).
# XENBUS_PATH path to this device's details in the XenStore (required).
#
# Read from the store:
# ip list of IP networks for the vif, space-separated (default given in
# this script).
#============================================================================

dir=$(dirname "$0")
. "${dir}/vif-common.sh"
netdev=enx8cae4cd6c871
main_ip=$(dom0_ip)
case "${command}" in

${metric}
done

log debug "Successful vif-route ${command} for ${dev}."
if [ "${command}" = "online" ]
then
success
fi

this line :

echo "/usr/sbin/arp -i enx8cae4cd6c871 -Ds $ip enx8cae4cd6c871 pub"

it seems wrong,but I don't understand how to fix it. $ip should be 192.168.1.14
and it takes it from here :

vif = [ 'type=vif,mac=00:16:3e:xx:xx:xx,script=vif-route-local,ip=192.168.1.14'
]

so basically it assign to the network interface called "enx8cae4cd6c871"
(that's on the host os (devuan) IP 192.168.1.14 ; it's a share that this does
not happen. There is something wrong. I think 192.168.1.14 should be assigned
to the vif network interface ? If it works like this,this does not
haopens,because both the interfaces came out with IP 1.3 :
