[one-users] MAC_PREFIX Can not be overrided by the VirtualNetwork template

[tedbs]

A side issue: shouldn't the MAC address begin with an even number? For example, "10:03" instead of "11:03".

Hello,

There is no MAC_PREFIX parameter in virtual network definition, only
in oned.conf and is global for all networks. If you want to specify
mac addresses with different prefix for an specific network you will
have to use "FIXED" type and set the mac address for each lease:

--8<------
LEASES = [IP=130.10.0.1, MAC=50:20:20:20:20:20]
LEASES = [IP=130.10.0.2, MAC=50:20:20:20:20:21]
------>8--

Bye
