<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>
