Bridge in Linux erstellen und Interface für VM hinzufügen, welches mit der Bridge verbunden wird.

ip link add name bridge0 type bridge
virsh attach-interface --domain bsd2vm2 --type bridge --source bridge0 --config

Um Mehrere Queues für ein Interface zu verwenden, driver Element hinzufügen (Config von bsd2vm1).

<interface type='bridge'>
  <mac address='52:54:00:b1:a0:5f'/>
  <source bridge='bridge0'/>
  <model type='virtio'/>
  <driver name='vhost' queues='3'/>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
</interface>
