+
+ <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>
