[one-users] Network Configuration - IP assignment

[Javier Fontan]

Hello,

Even if the VM's wont get the IP's form OpenNebula the MAC address
must be generated. Internally MAC addresses are tied to Virtual
Network leases so a place in a Virtual Network is needed. Just add a
class B or C network and everything should work ok.

You can also manually generate the mac addresses and you wont need the
Virtual Network, in VM template:

NIC=[MAC="00:02:01:23:45:67", IP="10.0.0.1", BRIDGE="br0"]

But this is more cumbersome as you will need to manually generate
different mac addresses for every interface.

Bye
