2.press F12  after qemu-kvm started

3.check boot order 

Actual results:
wrong boot list(bootindex option doesn't work)

Expected results:
bootindex works

Hi XiangChun,

Can you list the detail order that you expected? I checked the attachment and tested with upstream, the order is right.

Re-tested this bug with comment 0, and double-check boot list via F12. Boot order is right. Bootindex option works well. Understanding is wrong before. Anyway, I think you can close this bug now.

Thanks for your confirm.
