[root@lvs2 network-scripts]# ifup ens32:0
ERROR     : [/etc/sysconfig/network-scripts/ifup-eth] Error, some other host (00:0C:29:67:4A:E6) already uses address 192.168.100.100.

解决方法：
注释文件的内容

[root@dr2 ~]# vim /etc/sysconfig/network-scripts/ifup-eth

                   # if [ $? = 1 ]; then
                    #    ARPINGMAC=$(echo $ARPING |  sed -ne 's/.*\\[\\(.*\\)\\].*/\\1/p')
                     #   net_log $"Error, some other host ($ARPINGMAC) already uses address ${ipaddr[$idx]}."
                      #  exit 1
