[one-users] ubuntu-image from marketplace doesn't get an IP

[Javier Fontan]

virbr0 is a bridge automatically created by libvirt and is not
associated to any physical interface (vnet0 is not a physical
interface). You should create a new bridge or associate a physical
interface to virbr0. I think it is better to create a new one. If you
are using ubuntu you can find more information in these two guides:
