Description of problem:

i would like if libvirt could bind vnet devices on different namespaces

i would like to segment different bridges (linux bridges) on namespaces. so i can, for example, put all vm connected to certain vlan, and the bridge where them connect, on a specific namespace.
i would ideally create as many namespaces as vlans.

that should be a configuration option, off by default. 

    <interface type='bridge'>
      <mac address='52:54:00:10:e9:e3'/>
      <source bridge='br0'/>
      <target dev='vnet0'/>
      <namespace='foo'/>
    </interface>


i would set this bug as wishlist item.

thanks
