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!
