I have my KVM guests on br0 interface so I think its a bit different, but here is my two scripts I made.
Note to use ARP you first need to have the MAC in your Arp Table. Therefor its best to use fping to do a quick ping of entire network (takes like 2 seconds). This makes sure your Arp cache is up to date.
apt-get install fping yum install fping
Find a single guest IP via :
cat << 'EOF' > ~/findip.sh
#!/bin/bash
#FreeSoftwareServers.com
echo "Finding All Active IP's in Network via single Ping"
sleep 2s
fping -a -g 192.168.1.0/24 >/dev/null 2>&1 &
#nmap -sn 192.168.1.0/24 >/dev/null 2>&1 &
echo "Please Enter the Exact Name of the VM Guest:"
read guestname
arp -na | awk -v mac=$(virsh domiflist $guestname | awk '$2=="bridge"{print $NF}') '$0 ~ " at " mac {gsub("[()]", "", $2); print $2}'
EOF
chmod +x ~/findip.sh
sudo sh -c 'echo "alias findguestip=~/findip.sh" >> ~/.bashrc'
source ~/.bashrc
findguestip
Find All Guest IP's via:
cat << 'EOF' > ~/findallips.sh
#!/bin/bash

echo "Finding All Active IP's in Network via single Ping"

#nmap -sn 192.168.1.0/24 >/dev/null 2>&1 &

virsh list --all | grep running | cut -c 8- >> "$domainlog"
sed -i 's/running*//g' "$domainlog"
readarray domain < "$domainlog"
for i in "${domain[@]}"
do
ip="$(arp -na | awk -v mac=$(virsh domiflist $i | awk '$2=="bridge"{print $NF}') '$0 ~ " at " mac {gsub("[()]", "", $2); print $2}')"
echo "Hostname : $i IP : $ip"
done
rm "$domainlog"
