+      For hypervisors which support this, you can set the model of

+
+    <p>
+      The values for <code>type</code> aren't defined specifically by
+      libvirt, but by what the underlying hypervisor supports (if
+      any).  For QEMU and KVM you can get a list of supported models
+      with these commands:
+    </p>
+
+<pre>
+qemu -net nic,model=? /dev/null
+qemu-kvm -net nic,model=? /dev/null
+</pre>
+
+    <p>
+      Typical values for QEMU and KVM include:
+      ne2k_isa i82551 i82557b i82559er ne2k_pci pcnet rtl8139 e1000 virtio
