Using MAC Addresses
The easiest way to familiarize yourself with MAC addresses is to set the MAC address
statically, then remove the virtual machine configuration file options
ethernet<number>.address, ethernet<number>.addressType and
ethernet<number>.generatedAddressOffset. Check to see that the
virtual machine gets a generated MAC address.
We cannot guarantee that a host stays within a specific MAC address range. However,
we guarantee that the MAC address never conflicts with any physical host by using
our OUIs (00:0C:29 and 00:50:56), that are unique to virtual machines.
