[Xenomai-core] Xen/Xenomai

Hi All,

 

Is there any relationship between Xenomai and the Xen virtualization
monitor(http://www.cl.cam.ac.uk/Research/SRG/netos/xen/)? 

 

Would it make sense to port (or to integrate) Xenomai in such virtual
environment? (the notion of a Xenomai domain might correspond to a
virtual machine).

I would rather say that both are means to create domains (in the 
general sense of the term, cf. ISO RM-ODP), but of a different 
nature. In Xenomai objects in domains are tasks, in Xen objects 
are operating systems / virtual machines. IMHO, I don't see how 
they could fit together.

Why you think that Xen and Xenomai can't fit together?
As far as i know Xen and Adeos are very similar goals.

None, except that both provide virtualization services, but on a 
different scale.

Running Xenomai in a Xen domain aside of Linux should be possible 
without much trouble by connecting the HAL to the hypervisor, I think. 
Maybe another option would be to keep Xenomai as a Linux sub-system like 
now, but use Xen's paravirtualization to provide what's currently 
obtained from Adeos.

IIRC, people at Sombrio Systems are working on providing RTOS 
virtualization services on top of either Xen or Xenomai for embedded 
systems: http://www.linuxdevices.com/news/NS3509840836.html.
