Attional info(other tests): 1.Boot guest with hard disk(bootindex=1),CDROM(bootindex=2) and " -boot strict=on".Guest tried boot from Hard disk-->CDROM 2.Boot guest with hard disk(bootindex=2 ),network(bootindex=3),CDROM(bootindex=1)and "-boot strict=on" Guest tried boot from CDROM-->Hard disk-->network 3.Because fix is only for New interface (bootindex), so only test with "bootindex". According to above test ,this bug fixed. Reproduce this bug as follow version: Version: Host: # uname -r 2.6.32-405.el6.x86_64 # rpm -q qemu-kvm qemu-kvm-0.12.1.2-2.382.el6.x86_64 # rpm -q seabios seabios-0.6.1.2-26.el6.x86_64 Steps: 1.Boot guest (Hard disk(bootindex=1),CDROM(bootindex=2)) /usr/libexec/qemu-kvm -M rhel6.5.0 -m 4G -smp 4 -device virtio-scsi-pci,bus=pci.0,addr=0x5,id=scsi0,indirect_desc=off,event_idx=off -drive file=/home/test55.qcow2,if=none,id=drive-scsi0-0-0,media=disk,cache=none,format=raw,werror=stop,rerror=stop,aio=threads -device scsi-hd,drive=drive-scsi0-0-0,bus=scsi0.0,scsi-id=0,lun=0,id=flang,bootindex=1 -spice port=5830,disable-ticketing -vga qxl -qmp tcp:0:5555,server,nowait -global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0 -serial unix:/tmp/tty1,server,nowait -boot menu=on -monitor stdio -drive if=none,id=drive-cd-disk-1,media=cdrom,format=raw,cache=none,werror=stop,rerror=stop -device scsi-cd,drive=drive-cd-disk-1,bus=scsi0.0,id=scsi_cd2,bootindex=2 -device virtio-scsi-pci,bus=pci.0,addr=0x6,id=scsi1 -netdev tap,vhost=on,id=hostnet0 -device virtio-net-pci,netdev=hostnet0,mac=00:10:20:2c:45:23,bus=pci.0,addr=0x4,id=net0 Results: 1)Boot from Hard disk-->Tried CDROM--->Tried CDROM--->Tried network...
