We report our experience Guest OS (e.g., Windows, Linux) implementing SoulPad and using it on a variety of hardware configurations. We address challenges Encrypted Virtual Machine (x86 PC) common to systems similar to SoulPad, and show that the SoulPad model has significant potential as a Virtual Machine Monitor (VMware Workstation) mobility solution. -

Dynamic Migration of Computation Through Virtualization of the Mobile Platform
Dynamic Migration of Computation through Virtualization of the Mobile Platform Shivani Sud, Roy Want, Trevor Pering, Kent Lyons, Barbara Rosario, Michelle X. Gong Future Technology Research, Intel Inc 2200 Mission College Blvd Santa Clara, CA 95024 {shivani.a.sud, roy.want, trevor.pering, kent.lyons, barbara.rosario, michelle.x.gong}@intel.com Abstract Virtualization and live migration techniques have long been used in the enterprise server space and have been tuned to address data center usages. These capabilities are now expanding to personal computers including desktops and laptops and more recently into smaller mobile devices such as Netbooks and Mobile Internet Devices (MID). Hardware support for virtualization in these platforms, such as that offered by Intel® Atom™ processor, enables the use of existing operating systems and virtualization software. Our experiments demonstrate that live migration can be used to dynamically offload computation to a nearby desktop computer from a Netbook, taking only 25 seconds over a 100Mbps Ethernet network and approximately 100 seconds over an 802.11n interface with a measured throughput of 70Mbps. Additionally, these experiments highlight the limitations of existing virtualization solutions for migrating computation between small form-factor mobile devices and desktop computers which have widely varying resources and processing capabilities. Finally, we discuss the challenges observed in these early experiments and raise key questions that need to be resolved to enable the design of effective systems that support this use model. Keywords: Virtualization, MIDs, Intel® Atom™ processor, mobile, Virtual Machine (VM), live migration 1 Introduction In this paper, we discuss the use of virtualization on small mobile computers such as smart phones, Mobile Internet Devices (MIDs) and Netbooks which are increasingly enabling low-power high- performance computing in a small portable device form factor. -
