Correct. Just noticed that the default option use64 is 1. >> I guess 64bit OS might also be important.

Installers are different case - the issue may not occur with installers.
It is easiest to reproduce the issue on a given configuration. I think I gave a pretty concise description of our case. To reproduce the problem get: A Centos 5.8 64bit Linux (Centos 5.5 fails in the same way as well) Get the latest qemu checkout (alternatively qemu 1.3.0 and 1.2.0 fail in a very similar way as well) Try running /usr/bin/qemu -enable-kvm -m 4096 -smp 1,sockets=1,cores=1,threads=1 -name Cent5 -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/Cent5.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=readline -rtc base=utc -boot c -drive file=/patch_to_centos_5_8.ing,if=none,id=drive-ide0-0-0,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -vnc 127.0.0.1:0 -k en-us -vga std -device ivshmem,size=128M,use64=1,shm,bus=pci.0,multifunction=on,addr=0x5.0x0 -device virtio-balloon-pci,id=balloon0,bus=pci.0,multifunction=on,addr=0x4.0x0 and your guest will either hang or qemu process be terminated with an assertion message.
