LGTM.
Patched and built on an ubu-16.04 box.
I was able to log into both qemux86-64 and qemuppc
using core-image-minimal.
As people might expect, loads has changed:
qemu.git $ git diff v2.12.0..v3.0.0| diffstat| tail -1
1825 files changed, 101360 insertions(+), 46333 deletions(-)
Have you tested all of the oe-core qemu archs with the upgrade?
Any concerns other than what is listed here:
