Actually it only uses XC_PAGE_SIZE and the endianness is the host endianness. > Yup. It's still accel=xen just with no VCPUs. Are you talking about introducing accel=xen to Wei's target-null? I guess that would work OK. On the other hand if you are thinking of avoiding the introduction of a new target-null, how would you make xen_machine_pv.c available to multiple architectures? How would you avoid the compilation of all the unnecessary emulated devices?
