So yes, as you discovered the hard way, FreeBSD 13 requires a matching loader in order to work correctly with Xen. This is due to: https://cgit.freebsd.org/src/commit/sys/x86/xen/pv.c?id=b6d85a5f51e4147452b35d76478fb9e191b7734b As a user, where d oyou think it would be helpful for you to find this information, in the Xen handbook chapter maybe? https://docs.freebsd.org/en/books/handbook/virtualization/#virtualization-host-xen Thanks, Roger.
