Yes, since I tested qemux86/qemux86-64 with default tune, and everything is ok.
I don't think we should apply the Python workaround to oe-core as everyone will suffer for a configuration that is known to be broken (and isn't enabled in oe-core).
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 //Hongxu
