Notice FPU indicates yes and I requested -fpu on the command line.

I think it detects the host fpu as a 487 coprocessor. Anything in dmesg about it? Note there's no fpu in the flags: line.

That's a kvm kernel bug.

also is this a 486 as it says AMD?

You can override it if you like, -cpu 486,vendor=AuthenticAMD (I think).


Sorry - I thought the " -cpu 486,-fpu " was the way to turn off the fpu.
I 'm trying to emulute a 486 sx that has no fpu.

I thought so too, but in fact it emulates a 486sx+487. We can make it emulate a 486sx without a 487, but that will take a kernel patch.
