Qemu segmentation fault linux guest

[Jan Lambertz]

Hello,
I try to run a qemu  linux guest ontop of my openbsd 5.1 i386. I've tried
nearly any possible qemu command. I've tested archlinux,debian,sled and
ubuntu. In every case,qemu core dumps when loading the linux kernel. When i
run an openbsd guest with same qemu configuration, everything works
fine.ami missing something general ? No-acpi and vlan tweaks tested
with no effect.
My system has no hardware virtualisation support. Intel D525 cpu.
