[one-users] Problem with MAC_PREFIX

[Shankhadeep Shome]

You can only use the top 2 most significant bytes, the other 4 are reserved
for the ip to mac conversion open nebula does, the most significant byte is
set to 02: because the second bit should be set to 1 for locally
administered mac addresses 000000[1]0 : 00000000

I suggest you use mac prefixes like 02:01, 02:02 etc..
