Sierraware introduces a paravirtualization hypervisor for ARM architectures

The open source SierraVisor Hypervisor from Sierraware allows multiple operating systems, such as Linux, BSD, or Android, to run concurrently on any ARM11, Cortex-A9, or Cortex-A15 platform. With SierraVisor, guest systems can still access the secure world provided by ARM TrustZone technology, so each guest system can protect sensitive data like digital rights managed applications, encryption keys, and payment card data.

SierraVisor’s paravirtualization technology minimizes modifications to existing software and applications. A small number of non-intrusive hypercalls are inserted into the guest operating systems, reducing overhead at run-time. SierraVisor also offers robust multicore management, supporting both symmetric and asymmetric multiprocessing to manage system utilization.

The SierraVisor Hypervisor:

  • Extends the life of applications by simulating the previous generation of hardware. Equipment vendors can swiftly migrate to new processors without porting existing software.
  • Allows legacy real time operating systems to run simultaneously with new open source platforms like Linux, BSD and Android.
  • Streamlines development by supporting SMP and AMP process management.
  • Reduces hardware costs by enabling a single device to perform multiple functions such as data plane and control plane processes.
  • Maximizes availability by segmenting critical processes running on one guest operating system from less essential processes running on another guest operating system or mirror applications on different operating systems for redundancy.
  • Secures sensitive data with a Trusted Execution Environment (TEE) available for every guest operating system.

SierraVisor and SierraTEE are available for download under the GNU General Public License (GPL) at: http://www.openvirtualization.org. Users can connect with other Open Virtualization developers at: http://www.openvirtualization.org/board.

For a commercial, licensed version of SierraVisor, contact Sierraware at sales@sierraware.com . Technical support, professional services, and porting services are also offered by Sierraware’s ARM development experts.
