So may question was not if it's possible but if having target_ulong different from what wehad in qemu-system-ppc could cause any problems? I have no experience running 32-bitguests with qemu-system-ppc64 but previously when this came up one difference pointed outwas that target_ulong would change if I remember the discussion correctly, but nobody nowif that could be a problem.

It shouldn't be a problem. We take care of NARROW_MODE, so that you can boot a ppc64guest kernel, and then run ppc32 user binaries under that.


If you do find a bug under those conditions, report it.
