Hi There is file called libvirt.xml.template /usr/lib/python2.7/dist-packages/nova/virt/libvirt.xml.template you can copy it for example to /etc/nova and add next line to nova.conf --libvirt_xml_template=/etc/nova/libvirt.xml.template Also you should disable using virtio for bridges --use_virtio_for_bridges=false >From this template libvirt configuration files are generated - so to use e1000 driver you should add next line to this template - <model type='e1000'/> in bridge definition.
