Description of problem: core dumped when starting vm with pci addr > 0x20 Version-Release number of selected component (if applicable): qemu-kvm-0.12.1.2-2.108.el6.x86_64 How reproducible: frequently Steps to Reproduce: 1. start vm with (pci addr = 0x92, 0x93) qemu-kvm -name 'vm1' -chardev socket,id=human_monitor_f5dI,path=/tmp/monitor-humanmonitor1-20100810-181354-WbJi,server,nowait -mon chardev=human_monitor_f5dI,mode=readline -chardev socket,id=serial_Zm5R,path=/tmp/serial-20100810-181354-WbJi,server,nowait -device isa-serial,chardev=serial_Zm5R -drive file='/tests/kvm/images/RHEL-Server-5.5-PAE-virtio.qcow2',index=0,if=none,id=drive-virtio-disk1,media=disk,cache=none,snapshot=on,boot=on,format=qcow2,aio=native -device virtio-blk-pci,bus=pci.0,addr=0x92,drive=drive-virtio-disk1,id=virtio-disk1 -device virtio-net-pci,netdev=idopXlAo,id=ndev00idopXlAo,mac='02:B7:5E:9A:35:8a',bus=pci.0,addr=0x93 -netdev tap,id=idopXlAo,ifname='virtio_0_8000',script='/tests/kvm/scripts/qemu-ifup-switch',downscript='no',vhost=on -m 4096 -smp 2 -vnc :0 -spice port=8000,disable-ticketing -rtc base=utc,clock=host -M rhel6.0.0 -usbdevice tablet -cpu qemu64,+sse2 -no-kvm-pit-reinjection 2. 3.
