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.

+ +

On the x86 front most of the Xen work during this quarter + was focused on reworking the implementation of PVH inside of the + Xen hypervisor, so most of the activity during this quarter + happened inside of the hypervisor. Patches for a clean PVH + implementation have been posted, with the aim of having them + merged in the next Xen release (4.7). Once that's done, work will + continue on adding new features to both &os; and Xen in order to + have feature parity with traditional PV guests/hosts.

+ +

Apart from this, work is ongoing to import a new netfront + from Linux in order to support new features, like split event + channel and multiple queue support.

+ +

On the ARM front, this quarter's work focused on getting + &os;/arm64 booting as Xen guest. The current activity is to + upstream patches preparing Xen drivers to support arm64; this + includes a rework of the console driver.

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

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

+ + + +

Improve backend (netback, blkback) performance.

+ + + +

Work with upstream Xen to improve PVH and make it stable.

+ + + +

Improve the generic bounce buffer code for unmapped bios in + order to support the alignment requirements of the + blkfront driver.
