Motorola's QA4 touchscreen slider smartphone is the first commercially available phone to feature virtualisation.

Mobile features hypervisor
The device features Open Kernel Labs' OKL4 embedded hypervisor, which enables Linux and a real time operating system to run concurrently on one ARM processor. Apart from separating GPL and proprietary software code, the move also reduces the phone's bill of materials by $15.

According to OK Labs, the isolation provided by OKL4 when running concurrent operating systems on one processor is the same as running each operating system on a separate processor.
