I have one solution. Attach a storage to each domain.

1 ) attach a storage of 1G to each domain.
2 ) mount this file to dom0.
3) put dom0 ip into this.

4) In Domu create a init.d script. that ping the dom0 at startup using the dom0 ip at storage location.
5) In dom0  "arp cache u can get the ip of the domU ....u can identify this using the domu mac address.

# arp -a | grep -i <domU mac>

Try this looks fine. IF domU reboot then if IP chnages still at bootup init.d script will run and in dom0 aro cache u will get the new ip address.

Hello All

How to know the ip of domU , being present in dom0 console.?

Present i am having dom0 and one domU up and running. domU is getting ip address from dhcp.

But my question stays , Is there any way to know the ipaddress of domU without logging into domU.
it will be good if i get any api or command which i can kick in dom0 and get the ip of domU.
