[yocto] qemu not getting dhcp question.

[Insop Song]

Hi all,

I've built a new meta layer image based on core-image-minimal and
core-image-sato.

After the successful build, whey I run "runqemu" with the image, my
qemu image won't get a dhcp IP.
I can manually assign IP after the boot up.

Does anyone know why or which log to look at?

Here is the message from qemu
