That sounds like a great way to use real ARM boards for OBS. Does anyone feel like giving it a try? :) Alex Begin forwarded message:

From: Anup Patel <anup@brainfault.org> Subject: [Android-virt] [ANNOUNCE] [OFFTOPIC] Xvisor ARM with and/or without virtualization extensions Date: 24. April 2012 15:36:34 MESZ To: linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org, android-virt@lists.cs.columbia.edu, beagleboard@googlegroups.com, xen-arm@lists.xensource.com

Xvisor (eXtensible Versatile hypervISOR) is an open source bare-metal monolithic hypervisor, which aims towards providing virtualization solution, which is light-weight, portable, and flexible with small memory foot print and less overhead. It is distributed under GNU Public License (GPLv2).

Xvisor has most of the features expected from a modern full-fledged hypervisor, such as: - Tree based configuration - Tickless and high resolution timekeeping - Wall-clock for tracking real-time - Threading framework - Host device driver framework - CPU virtualization - Address space virtualization - IO device emulation framework - Pass through hardware access - Dynamic guest creation/destruction - Serial port virtualization - Management terminal

The ARM port of Xvisor (or Xvisor ARM) supports a wide range of ARM processors namely: - ARM9 (Boards: VersatilePB) - Cortex-A8 (Boards: Realview-PB-A8) - OMAP3 (Boards: BeagleBoard-xM) - Cortex-A9 (UP) (Boards: Vexpress-A9) - Cortex-A15 (UP) Without VE (Boards: Vexpress-A15) - Cortex-A15 (UP) With VE (Boards: Vexpress-A15)

For all supported ARM processors Xvisor ARM is able to boot multiple unmodified Linux-3.0.4 guest with a fairly interactive and smooth Busybox 0.19.2 console.

On real hardware specifically BeagleBoard-xM (OMAP3 @ 600 MHz) we get near native CPU performance (i.e. Native Linux 3.0.4 gives 1120 DMIPS whereas Linux 3.0.4 running as guest on Xvisor ARM gives 960 DMIPS)

Please try out our Xivsor Cortex-A15 demo on ARM Fast Models 7.0 and/or Linaro QEMU (2.02 or higher). To download the demo tarball visit: https://docs.google.com/open?id=0B0ABS_s60oP_WjNQQ0QtUzNmdmc
