To answer the original questions<br>
<br>
>> Is it currently possible to run rtems as an application on top of linux or FreeBSD? I have an where I need to simulate multiple instantiations of rtems and would benefit from running native.<br>
We are using Qemu to run our RTEMS applications and I think it is just fine for the use case you are describing. You can start multiple instances of Qemu running the same or different RTEMS applications.<br>
For communication between the different instances you can either use a socket-based interface using the emulated network between the different instances or use shared memory as documented here: <a href="http://wiki.qemu.org/TexiDemo#Inter-VM_Shared_Memory_device" target="_blank">http://wiki.qemu.org/TexiDemo#Inter-VM_Shared_Memory_device</a><br>

>> If not, are there any major show stoppers in developing a BSP for running rtems as a thread on top of another OS?<br>
</div>Qemu does not bring so much overhead and runs almost as fast as native. Moreover, Qemu already offers advanced functionalities for debuging for example. I don't think that the overhead of developing your own BSP/port to run RTEMS natively as a userspace application is worth.<br>

Ralf/Chris, The original poster was asking a different question about<br>
executing RTEMS within a host OS environment.<br>
<br>
For reference the conversation about a way to do it:<br>
