libvirt users - Jan 2018 - domain xml does not have <target dev='vnetX'/>

Hi I'm trying to monitor bandwidth usage of a KVM VM but couldn't find
<target
dev='vnet0'/>
on virsh edit domain_name

all i get is this

    <interface type='network'>
      <mac address='52:54:00:a1:05:b6'/>
      <source network='vmango'/>
      <model type='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00'
slot='0x03'
function='0x0'/>
    </interface>

how do i determine which vnet is connected to which domain?

The vnet name is dynamically allocated when the VM is started. virsh edit
modifies the *inactive* configuration, so that doesn't include the vnet
device name. You need 'virsh dumpxml' while the guest is running, to be
able to see the vnet name.
