+    <body>
+      <p>Xen is a hypervisor using a microkernel design, providing
+	services that allow multiple computer operating systems to execute
+	on the same computer hardware concurrently.  Xen support for &os;
+	on x86 as a guest was introduced in version 8 and ARM support is
+	currently being worked on.  Support for running &os; as an amd64
+	Xen host (Dom0) is available in HEAD.</p>
+
+      <p>On the x86 front most of the Xen work during this quarter
+	was focused on reworking the implementation of PVH inside of the
+	Xen hypervisor, so most of the activity during this quarter
+	happened inside of the hypervisor.  Patches for a clean PVH
+	implementation have been posted, with the aim of having them
+	merged in the next Xen release (4.7).  Once that's done, work will
+	continue on adding new features to both &os; and Xen in order to
+	have feature parity with traditional PV guests/hosts.</p>
+
+      <p>Apart from this, work is ongoing to import a new netfront
+	from Linux in order to support new features, like split event
+	channel and multiple queue support.</p>
+
+      <p>On the ARM front, this quarter's work focused on getting
+	&os;/arm64 booting as Xen guest.  The current activity is to
+	upstream patches preparing Xen drivers to support arm64; this
+	includes a rework of the console driver.</p>
