libvirt doesn't support 'gatewaydev'.  I'm certainly no expert in this area, but 
is it possible to convert your host config in boot.local to a libvirt routed 
network [1] and then have the guest use it with something like
  <interface type='network'>
    <source network='boot.local.equiv'/>
    ...
  </interface>
