As of 2.04-8 it was possible to boot Xen on ARM. The funky mechanism by which GRUB loads its modules does a good job of obscuring which modules to confirm presence of.
Seeing 'xen_loader="xen_hypervisor"' makes one expect to find "/usr/lib/grub/arm64-efi/xen_hypervisor.mod", not for it to be taken care of by "/usr/lib/grub/arm64-efi/xen_boot.mod". -- (\___(\___(\______ --=> 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
