+    <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>Regarding x86, the work done during this quarter has been
+	focused in rewriting the PVH implementation inside of Xen, to what
+	is now being called HVMlite (in order to differentiate it with the
+	previous PVH implementation).  The Xen side of patches have
+	already been committed to the Xen source tree, and will be
+	available in Xen 4.7 (the next version).  Work has also begun on
+	implementing HVMlite Dom0 support, although no patches have yet
+	been published.</p>
+
+      <p>HVMlite support for &os; has not yet been committed,
+	although an initial implementation is available in a personal git
+	repository.  The plan is to completely replace PVH with HVMlite on
+	&os; as soon as HVMlite supports Dom0 mode.</p>
+
+      <p>Apart from this, Wei Liu is working on improving netfront
+	performance on &os;; initial patches have been posted to the &os;
+	review system.</p>
+
+      <p>During this time frame, the x86 unmapped bounce buffer code
+	has also been improved, and unmapped IO support has been added to
+	the <tt>blkfront</tt> driver.</p>
