Virtual MAC Addresses

[IanSeyler]

Does anyone have experience with using Virtual MAC addresses in their operating systems?

In my Parallax system I have set it to the following:

Node 1 Physical MAC: 08:00:c4:73:56:04
Node 1, Core 1 Virtual MAC: 08:00:c4:73:56:05
Node 1, Core 2 Virtual MAC: 08:00:c4:73:56:06

Will I need to modify the NIC driver to listen on multiple MAC's (The Intel 8254x supports up to 16) or just set it to promiscuous?

How does something like VMware do it?
