As usual, you can try the following methods: 1. log in the guest then ifconfig I guess it's not what you want 2. filter /var/lib/dnsmasq/dnsmasq.leases file according to actual guest mac address 3. using nmap to scan guest subnet paste the following shell codes into mac2ip.sh: #! /bin/bash if [ $# -ne 2 ]; then echo "Usage: $(basename $0) <SUBNET> <MAC>" exit 1 fi SUBNET=$1 MAC=$2 rpm -q nmap > /dev/NULL if [ $? -ne 0 ]; then echo "you need install nmap" exit 1 fi if [[ -n $SUBNET ]]; then OUTPUT=$(nmap -sP -n $SUBNET | grep -i -B 2 $MAC) if [[ -n $OUTPUT ]]; then IP=$(echo $OUTPUT | sed -e 's/.* \([0-9]*\.[0-9]*\.[0-9]*\.[0-9]*\).*/\1/') fi fi echo $IP And then run the following cmdline: % mac=$(virsh dumpxml ${your domain name} | grep "mac address" | awk -F"'" '{print $2}' | head -1) % subnet=$(ip route | grep "${your guest interface}" | sed -n 1p | awk '{print $1}') % sh mac2ip.sh $subnet $mac Note: for instance, your guest name is 'foo', and interface is 'virbr0' Good Luck!
