BTW, is there a preferred 'set' of options to feed ./configure?

No.

I used
'./configure --prefix=/opt/kvm --enable-kvm' to build.

Finally got my system (Smoothwall/Roadster) stabilized and out the door, so I
have time to dedicate to this.

OK. I've built 0.14 (installed to /opt/kvm and I deleted Squeeze's older
package) and am using Squeeze's kvm_amd module. I tried without -cpu and -smp;
I tried -cpu qemu64. I eliminated the -vga and -serial options to no avail. It
still chokes on 1005MB RAM.


Works for me.  Please use -monitor stdio and issue the commands

(qemu) info registers
(qemu) x/50i $eip - 30

So what's the next ste... ... Wait, just thought of something to try: 'rmmod
kvm-amd'. ... Oho! Without the accelerator, it runs with at least 1588M RAM,
but can't allocate 2000M RAM (this may be expected on a 32-bit OS with PAE).

2G limit is expected on i386.

Does this help? Is it time to submit a debian bug?

If debian fixes the bug, that would be great.
