As describe here: https://lists.gnu.org/archive/html/qemu-devel/2017-02/msg06407.html It seems like this is still an issues. When i add the following to the configuration. The guest OS should be able to handle FPU divide by zero commands to the CPU. <cpu mode='custom' match='exact' check='partial'> <model fallback='forbid'>pentium</model> <topology sockets='1' cores='1' threads='1'/> <feature policy='force' name='vme'/> <feature policy='force' name='pse'/> <feature policy='force' name='fpu'/> <feature policy='force' name='de'/> <feature policy='force' name='tsc'/> <feature policy='force' name='msr'/> <feature policy='force' name='mce'/> <feature policy='force' name='cx8'/> <feature policy='force' name='mmx'/> </cpu> Running HWInfo32 shows But when using a 16 bit program, it breaks each time the FPU is divided by zero. This is supported by the CPU itself, but not Qemu it seems. There seem to be a workaround mentioned in here: https://github.com/cloudius-systems/osv/issues/855 But a proper fix should be implemented, so emulation is 100% correct.
