Yocto image qemuppc do not  boot and OS not load

Host Ubuntu 14.04 tested on 64 bits and 32 bits

Reproducing steps:
1) download qemuppc from autobuilder 
http://autobuilder.yoctoproject.org/pub/releases/yocto-1.7.rc3/machines/qemu/qemuppc/
2) build environmemt
 build oe-init-build-env
3) start qemuppc
  runqemu qemuppc or runqemu qemuppc core-image-sato-sdk or using the image path

Expecting output: Yocto image should boot and OS load 
  
The actual output:Qemu starts, but the qemu window is completely white.

The bug reproduce on Ubuntu 14.04 64 bits and 32 bits, but on Fedora qemuppc works perfectly fine

Hi Andra,
Can you please re-test this issue on the latest release candidate?

Thanks,
Cristian
Comment 2 Mihail Stanciu 2014-10-21 14:50:55 UTC 
Both sato and sato-sdk images exhibit this behaviour on RC5: 924da20c6f2f183fa7e930e4c3c6b14c090acbe5

Please note that this only happens with downloaded images from AB. 
On previous tests, if we built an image locally it worked perfectly. Have not built a local image on RC5 yet, but suspect behaviour still present.

Same as before, this only happens on Ubuntu 14.04 machines; on Fedora the AB image works.
Comment 3 Mihail Stanciu 2014-10-21 15:04:27 UTC 
Cristian has confirmed that using a locally built image works for RC5.

This suggests an issue with AB, in my opinion.
Comment 4 Yi Zhao 2014-10-22 07:24:58 UTC 
I can not reproduce this issue on my ubuntu 14.04 x86-64.
Here are the steps:
1. download qemuppc image from ab: http://autobuilder.yoctoproject.org/pub/releases/yocto-1.7.rc5
2. build poky environment
   source oe-init-build-env
   bitbake meta-ide-support

3. launch the qemuppc
   runqemu qemuppc  ~/qemuppc/vmlinux--3.14.19+git0+fb6271a942_73e2411cdd-r0-qemuppc-20141016220152.bin  ~/qemuppc/core-image-sato-sdk-qemuppc-20141018182036.rootfs.ext3

The system can boot without problem and the GUI is good.
Comment 5 Mihail Stanciu 2014-10-22 11:50:21 UTC 
Not a bug.
Further research after Yi's comment revealed we were missing a required step when using pre-built images to run qemu.
Comment 6 Mihail Stanciu 2014-10-22 11:51:00 UTC 
Closing.
