Virtualization - Running RTOS and UNIX on one machine

Virtualization - Running RTOS and UNIX on one machine

[Bin Chen]

Hi, 


It seems a very large marketplace for the virtualization in embedded 
field. Many works which need to be done by 2 or more processors can be 
done by only one processor if adopt a technique that allow a 
supervisor software to control both a UNIX OS(typically Linux) and a 
RTOS(or more?). 


I am very interested in this technology and I know there has been a 
lot of startup in this fields, such as http://www.virtuallogix.com/. 
And there are many open source virtualization project, such as XEN and 
OpenVZ, but I can't find a project for running a general purpose OS 
plus RTOS. 


Because RTOS has some constraints on timing, so I think there should 
be many differences between existing open source general purpose 
virtualization techniques and the commercial RTOS vitualization 
techniques. 


I really don't have enough experience on RTOS, so can anybody who are 
good at this can comment for is it very hard to make this done? 


Thanks for your comments! 


Bin
