Yeah, a few minutes of thinking and realized the situation and how silly I was being thinking this was likely possible out of the box.

In other news the Raspberry PI 4B has hardware which matches the profile for running Xen. There appears to be a distinct pool of people trying to run Xen on Raspberry PI devices (I'm not the only one, I think I've got rather more of a clue than most, doesn't mean I'm anywhere near perfect). -- (\___(\___(\______ --=> 8-) EHM <=-- ______/)___/)___/) \BS ( | ehem+sig...@m5p.com PGP 87145445 | ) / \_CS\ | _____ -O #include <stddisclaimer.h> O- _____ | / _/ 8A19\___\_|_/58D2 7E3D DDF4 7BA6 <-PGP-> 41D1 B375 37D0 8714\_|_/___/5445
