I've created a bridge on the host with a method similar to the one here:
However, to link the guest machine to the bridge, the doc suggests something like this in the libvirt config file:
<interface type='bridge'> <source bridge='br0'/> <mac address='00:16:3e:1a:b3:4a'/> </interface>
However, I do not want to use libvirt. How can this be achieved by specifying options to the command line on the creation of the guest via the 'kvm' command?
