<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>
