a terrible bash script that uses the ARP table to determine IP addresses for running KVM guests on a bridged interface

script.sh

#!/bin/bash
for vm in $(virsh list --state-running --name); do
  echo -n "$vm "
  arp | grep $(virsh domiflist $vm | sed '/^$/d' | tail -n1 | awk '{ print $NF}') | awk '{ print $1 }'
done

# $ script.sh
# vm1 192.168.1.100
# vm2 192.168.1.101
