[Libvir] New XML attributes for virtio

Hi! I filed https://bugzilla.redhat.com/show_bug.cgi?id=431063 yesterday to track this issue. Quoting the bug report: "To use the new virtio capabilites available in kvm 60, special command line paramaters need to be passed to kvm. There should be a way to specify that a device should use virtio in the libvirt xml. I propose adding a "model" attribute to the interface element in the XML to be able to specify the type of NIC to emulate, e.g. 'virtio'. For the disk virtio I propose adding an 'interface' attribute to target element (inside the disk element). This interface could then be set to 'virtio', 'ide', 'scsi', etc.." Since I wrote the bug report, I noticed there's no way to specify which graphics card, you'd like to emulate. A 'model' attribute could probably be added to the graphics element as well.
