at the console for the xenserve you can go into Network management interface configuration and arrow down the
list to the other nic and then configure the ip address of the second nc. The problem is that if you do this in xen
center console, it will make the last nic you configured the management interface, so you may have to then re-
connect on that other ipaddress, so this is best done from the xenserver console., when you have configured all
subsequent nics, go back and edit the first one again, so it becomes he management interface again.
