Not really, the Zones allowed a NIC alias to be used, rather than use the full NIC itself, this them provides Solaris Zones with the ability to use a limited amount of physical NICS, but allocate exclusive IP stacks to the Zones on the VNIC instead of using the entire original physical NIC. Aliases are totally different than VNICS, the NIC IP alias has been around in Solaris a long time, and was implemented in Linux after even that. The BSD's also have NIC IP aliasing as well. > > Please free to chime in. I'm undecided whether I really need crossbow, > but if I do I will have use at least snv_83.
