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> + </body> + + <sponsor> + Citrix Systems R&D + </sponsor> + + <help> + <task> + <p>Finish HVMlite Dom0 support inside of Xen.</p> + </task> + + <task> + <p>Deprecate and remove PVH support from Xen.</p> + </task> + + <task> + <p>Remove PVH support from &os; and switch to HVMlite.</p> + </task> + + <task> + <p>Generalize the event channel code so it can be used on + ARM.</p> + </task> + + <task> + <p>Improve the performance of the various backends + (<tt>netback</tt>, <tt>blkback</tt>).</p> + </task> + </help> + </project> </report>
