+ <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>
