Yes, since I tested qemux86/qemux86-64 with default tune, and everything
is ok.

Trace the issue costs a lot of time, the original failure was invoking
'smart update' in qemu, and found out the python md5/sha checksum
output incorrect, and then found out qemu86-64 with corei7-64 did
not support gcc optimization level 3 '-O3' very well [YOCTO #8748]
BTW, boot the same image with virtualbox, everything is ok
