Short answer: Most likely no one needed it yet. Therefore no one 
implemented or tested it.

I had a look at the XEN BSP: It has been added by Jeff Kubascik end of 
2019. He didn't seem to be very active since then but I added the mail 
address he used for the commits back then on CC so maybe he will provide 
some more information.

What did you try to enable it?

A clean way would be to check what startup code is used, whether there 
are some special drivers that might make problems and so on. But from a 
first glance, the BSP doesn't seem to use too much special stuff. So you 
might want to just try to turn on RTEMS_SMP during configuration and see 
what happens.

Best regards

Christian
