One approach is to always manually set the MAC address to the same as the IP that you intend to put on that interface. For example, if an LDom is going to have an IP address of 192.168.47.5, generate a MAC address with: $ printf 00:00:%02x:%02x:%02x:%02x `echo 192.168.47.5 | tr . ' '` 00:00:c0:a8:2f:05 This avoids the complication of having to maintain some sort of central registry. -- Mike Gerdts http://mgerdts.blogspot.com/
