Auto power off means the ubuntu container failed to start, and that 
could be related with a missing kernel config.

You can debug the issue by doing the following:
 * Make sure your kernel config has the additional configs described at 
https://wiki.ubuntu.com/Touch/Porting#Kernel
 * See if you're able to use the ubuntu rootfs chroot executing "adb 
root; adb shell; ubuntu_chroot shell"
 * See if you're able to start the container (with upstart), by 
executing "adb root; adb shell; ubuntu_chroot;"
