I'm trying to figure out how to use virsh (or something else) to list all the IP addresses (or MAC addresses if needed) for each virtual NIC, preferably with it domain affiliation also listed.
Is this possible?
== method 1: (simple but not reliable) # cat /var/lib/dnsmasq/dnsmasq.leases 1295343272 52:54:00:6f:2e:72 192.168.122.118 * * == method 2: # This script is to map MAC into IP, accepts two # arguments, subnet prefix and MAC address of the # interface. #! /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 e.g. for a guest which use libvirt "default" network, get the subnet like: # ip route | grep "virbr0" | sed -n 1p | awk '{print $1}' you could write automate script to parse the MAC address of domain interfaces, the bridge name, and the subnet prefix of bridge, and then use the script above the get the IP. And as Justin said, Rich has more clever tool to do it, I also forgot, you can wait him, :-) Regards Osier
