    Mac address pooling questions

    From Surgient documentation:MAC Address Range -- MAC addresses must be created. When a VM is deployed, a MAC address from this range provides the internal MAC address for the VM.In our environment, one of our development groups uses MAC addressing as part of an identifier for a machine.   How is the MAC address pooling applied when 1 Application configuration is deployed /initialized?   What happens when you have multiple copies of the same Application Configuration running?  Will Server Configurations of each copy of the Application Configuration get a different MAC address? At run time? If a Snapshot is taken, or a run of a Application Configuration is paused and shelved, will the individual Server Configurations retain their MAC addresses when the resume running?Will MAC addresses pass through the NAIL’d configurations firewall?  Or will the MAC be NAT’d?Is there a way to permanently attach a MAC to a specific Server Configuration?Thanks!

    A MAC Address is assigned to each deployed VM - and they are all unique (and must be so).  Unless you have used a RAM based snapshot, you are never guaranteed the same MAC address twice.  If you need to permanently attach a MAC to a specific server configuration, then you would use NAIL2 and assign the MAC Address.  It will allow the image to think it is using whatever MAC Address you supply, but the outside world will see the MAC Address assigned to the VM.
