Mobile virtualization

From Wikipedia, the free encyclopedia

Mobile virtualization is hardware virtualization on a mobile phone or connected wireless device. It enables multiple operating systems or virtual machines to run simultaneously on a mobile phone or connected wireless device. It uses a hypervisor to create secure separation between the underlying hardware and the software that runs on top of it; this can be considered a form of an embedded hypervisor, or a close analogue. Virtualization technology has been used widely for many years in other fields such as data servers (storage virtualization) and personal computers (desktop virtualization).

Applications[edit]

Low cost platform[edit]

In 2008, the mobile industry became interested in using the benefits of virtualization technology for cell phones and other devices like tablets, netbooks and machine-to-machine (M2M) modules.[1] With mobile virtualization, mobile devices can be manufactured more cheaply through the re-use of software and hardware, which shortens development time. One such example is using mobile virtualization to create low-cost Android smartphones without a separate baseband processor by running the applications and the baseband processor code in separate virtual machines on a single processor.[2] Semiconductor vendors such as ST-Ericsson have adopted mobile virtualization as part of their low-cost Android platform strategy.[3]

Enterprise[edit]

Another use case for mobile virtualization is in the enterprise market. Today, many consumers carry two mobile phones: one for business use and another for personal use. With mobile virtualization, mobile phones can support multiple domains/operating systems on the same hardware, so that the enterprise IT department can securely manage one domain (in a virtual machine), and the mobile operator can separately manage the other domain (in a virtual machine).[4]

In September 2010, ARM announced[5] that it would support a virtualization extension in its ARM Cortex-A15 processor.[6]
