This previous message from April contains the patch which added support for the <model type='...'/> element in NIC definitions. https://www.redhat.com/archives/libvir-list/2008-April/msg00078.html Unfortunately it looks like the documentation for it was applied to a generated file so it got lost along the way. The attached patch adds documentation in hopefully the right place. Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-top is 'top' for virtual machines.
