Please read it again. Nanokernels/hypervisors are not an RTOS. They do not schedule tasks or povide RT services. They only allow client OSes to share hardware. IBM has been doing this for over 30 years. As for RTAI, it is running side-by-side with another OS, it is not running under Linux in a master-slave relationship. I know things are polarized in this thread, but please avoid FUD.
