Webinar Q&A: Does the citrix client run in the smartphone OS or in the microvisor?

Thanks to everyone who attended our webinar on the Nirvana phone  I am a product manager at Open Kernel Labs and I will be answering a few of the questions that came in during the webinar that we were unable to answer in the allotted time.

I'll start off with this one:

Does the citrix client run in the smartphone OS or in the microvisor?

First of all, I would highly recommend a quick review the of Nirvana Phone white paper that is freely available for download at: The NirvanaPhone Concept Spec and Reference Architecture

In particular, see Figure 3 on page 7 showing a native design of the Nirvana phone.  In the native design, there is no virtualization technology and hence the native operating system has full control over the underlying hardware.  In this scenario, the Citrix receiver runs directly on the native operating system.  However, see Figure 4 on page 8 that shows a more flexible design using the OKL4 Microvisor.  In this case, OKL4 Microvisor is a thin embedded hypervisor that has full control over the hardware and hosts the native high-level smartphone OS.  Also, note that the Citrix receiver is ported to run directly on the OKL4 Microvisor.  The resulting architecture with OKL4 Microvisor is far more flexible, secure, and scalable compared to the native system architecture.

Hope this helps.  Please feel free to contact me if you have any further questions regarding the webinar or OKL4 Microvisor in general.
