Mobile devices, such as smart phones and tablets, are becoming de-facto everyday computing and communication devices, virtualization can bring additional benfits to mobile devices for both security and manageability. IT department may use hypervisor, as a highly secure solution, to manage autherized mobile devices, such as for network traffic monitoring, filtering, scan (for virus detection), and/or OS update/patching even when the guest OS becomes completely dead. We insert Xen to the mobile OS Android to deprivilege Android as guest for security and manageability purpose. However, the usage case of mobile device is quit different with that of server, for example mobile devices runs completely different benchmarks (mostly multimedia focused) vs. that in server (mostly responsiveness focused). We analyze the gap of Xen as a mobile hypervisor and present how we improve the performance.
