Comment 1 for bug 1512697

Workaround on VM side e.g. CentOS is to modify /usr/sbin/dhclient-script to disable arping

        if arping -D -q -c2 -I "${interface}" "${new_ip_address}"; then
            dhconfig
            exit_with_hooks 0
        else # DAD failed, i.e. address is already in use
            dhconfig
            exit_with_hooks 0
# ARP_REPLY=$(arping -D -c2 -I "${interface}" "${new_ip_address}" | grep reply | awk '{print toupper($5)}' | #cut -d "[" -f2 | cut -d "]" -f1)
# OUR_MACS=$(ip link show | grep link | awk '{print toupper($2)}' | uniq)
# if [[ "${OUR_MACS}" = *"${ARP_REPLY}"* ]]; then
# # the reply can come from our system, that's OK (#1116004#c33)
# dhconfig
# exit_with_hooks 0
            else
                exit_with_hooks 1
            fi
        fi
