Reproduce this bug as follow version:
Host:
# uname -r
3.10.0-84.el7.x86_64
# rpm -q qemu-kvm
qemu-kvm-1.5.3-37.el7.x86_64
# rpm -q seabios
seabios-1.7.2.2-11.el7.x86_64

Guest:rhel7

Steps:
1)Boot guest with CLI like comment0
2)Continue guest
(qemu)c
3)Press F12 see the seabios boot order and try boot guest

Results:DVD/CD  ranks 1.Guest will boot from DVD/CD in default
1. DVD/CD [AHCI/5: QEMU DVD-ROM ATAPI-4 DVD/CD]
2. Virtio disk PCI:3:0
3. Legacy option rom
4. iPXE (PCI 06:00.0)

Verify this bug as follow version:
Host
# uname -r
3.10.0-84.el7.x86_64
# rpm -q qemu-kvm
qemu-kvm-1.5.3-45.el7.x86_64
# rpm -q seabios
seabios-1.7.2.2-11.el7.x86_64

Guest:rhel7

Steps as same as reproduce

Results:The first is virtio disk, and guest work well
1. Virtio disk PCI:3:0
2. DVD/CD [AHCI/5: QEMU DVD-ROM ATAPI-4 DVD/CD]
3. Legacy option rom
4. iPXE (PCI 06:00.0)


Addtional info:
1)Also test boot guest with two disk and "-M q35",the boot order is correct
2)Also test boot guest with one disk and one scsi CDROM and "-M q35",the boot order is correct

According to above test ,this bug fixed.
