[one-users] Create a VM with specific MAC address

[Javier Fontan]

In your VM template you can specify an IP or a MAC in the NIC section:

NIC=[NETWORK=private,MAC=02:00:01:02:03:04]

But beware as this will also set the IP, last 4 bytes. The mac needs
to be in the network pool.

The easiest way is to set the the IP and let it generate the mac address:

PREFIX+IP=MAC

By default PREFIX is 02:00. IP will be added afterwards, the last 4
bytes. For example, IP 10.0.0.1:

02:00 + 10.0.0.1 (0a:00:00:01) = 02:00:0a:00:00:01
