+      <p>&os; Xen HVM can be further improved by using more PV
+	interfaces inside a HVM guest.  So far the following items have
+	been completed:</p>
+
+      <ul>
+	<li>Update Xen interface files.  (Merged into
+	  <tt>head</tt>)</li>
+	<li>Add support for the vector callback injection mechanism.
+	  This replaces the PCI interrupt and provides a per-cpu
+	  callback, which was not possible when using the PCI
+	  interrupt.</li>
+	<li>Rework event channel implementation and use the same code
+	  paths for both PV and PVHVM.</li>
+	<li>Implement PV one-shot event timers and timecounters.</li>
+	<li>Implement PV IPIs.</li>
+	<li>Live migration support for PV timers and PV IPIs.</li>
+      </ul>
+
+      <p>With this changes, &os; will have a complete PVHVM port, this
+	will also set the ground for a future PVH port (when PVH support
+	is merged into Xen).</p>
+
+      <p>Further improvements on blkfront and netfront have also been
+	commited:</p>
+
+      <ul>
+	<li>Fix netfront crash when detaching an interface.</li>
+	<li>Enable netfront to specify a maximum TSO length limiting the
+	  segment chain to what the Xen host side can handle after
+	  defragmentation.</li>
+	<li>Add barriers and flush support to blkfront.</li>
+      </ul>
+
+      <p>Netfront changes have been merged to <tt>stable</tt> branches,
+	blkfront changes are only in <tt>head</tt>.</p>
