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.

+ +

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.

+ +

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.

+ +

Apart from this, Wei Liu is working on improving netfront + performance on &os;; initial patches have been posted to the &os; + review system.

+ +

During this time frame, the x86 unmapped bounce buffer code + has also been improved, and unmapped IO support has been added to + the blkfront driver.

+ + + + Citrix Systems R&D + + + + +

Finish HVMlite Dom0 support inside of Xen.

+ + + +

Deprecate and remove PVH support from Xen.

+ + + +

Remove PVH support from &os; and switch to HVMlite.

+ + + +

Generalize the event channel code so it can be used on + ARM.

+ + + +

Improve the performance of the various backends + (netback, blkback).
