Description of problem:
if use the same bootindex option when hot-plug it, qemu will quit immediately.  

Version-Release number of selected component (if applicable):
# rpm -qa|grep qemu
qemu-kvm-tools-0.12.1.2-2.212.el6.x86_64
# uname -r
2.6.32-220.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1.# /usr/libexec/qemu-kvm -M rhel6.2.0 -m 4096 -smp 4,cores=2,threads=1,sockets=2 -cpu cpu64-rhel6,+sse2,+x2apic -name rhel6.2-64 -chardev socket,id=serial_id_20111215,path=/tmp/serial,server,nowait -device isa-serial,chardev=serial_id_20111215 -drive file=/home/win2008r2-sp1-3.qcow2,index=0,if=none,id=drive-virtio-disk1,media=disk,cache=none,format=qcow2,aio=native -device virtio-blk-pci,bus=pci.0,addr=0x4,drive=drive-virtio-disk1,id=virtio-disk1,bootindex=1 -device virtio-net-pci,netdev=idbEmLYK,mac=9a:3c:3a:f0:b4:1a,id=ndev00idbEmLYK,bus=pci.0,addr=0x3 -netdev tap,id=idbEmLYK,vhost=on -rtc base=utc,clock=host,driftfix=slew -boot order=cdn,once=d,menu=on -no-kvm-pit-reinjection -usb -device usb-tablet -enable-kvm -chardev socket,id=qmp_monitor_id_qmpmonitor1,path=/tmp/monitor-qmpmonitor1,server,nowait -mon chardev=qmp_monitor_id_qmpmonitor1,mode=control -spice port=5912,disable-ticketing -vga qxl -monitor stdio -drive file=/home/second-disk-3.qcow2,index=1,if=none,id=drive-virtio-disk2,media=disk,cache=none,format=qcow2,aio=native -device virtio-blk-pci,bus=pci.0,addr=0x5,drive=drive-virtio-disk2,id=virtio-disk2,bootindex=2

2.(qemu)device_del virtio-disk2

3.(qemu) __com.redhat_drive_add file=/home/second-disk-3.qcow2,id=drive-virtio-disk2,media=disk,cache=none,format=qcow2,aio=native
(qemu) device_add virtio-blk-pci,bus=pci.0,addr=0x5,drive=drive-virtio-disk2,id=virtio-disk2,bootindex=2
  
Actual results:
qemu quit, and show below info
Two devices with same boot index 2


Expected results:
add device successful

Seems like it (does not) works by design. Right Gleb?

Right. Exiting qemu during hotplug is not the best error handling though. We should fail hotplug but not kill a guest.

According t ocomment #3,re-open this bug .

comment #3 does not cancel the fact that the bug is invalid. You can't (and management should never try to) hotplug device with existing boot index either way. If you want you can open a bug with request to improve error handling.

I re-open a request bug(771545) with low severity and priority
