Git rev: master/6e20b31d5d17133e0fca086e12a0ad06ab5c4cc8

Steps:
1. Download poky source and set the environment.
2. Run bitbake meta-ide-support
3. Run bitbake core-image-sato
4. Set the environment for meta-ide-support
   $ . ./tmp/environment-setup-i586-poky-linux 
5. Run runqemu to launch a qemu image
   $ runqemu tmp/deploy/images/qemux86/core-image-sato-qemux86.qemuboot.conf 

The qemu can be launched but the ip address is not correct. The root cause is sudo command is not in the PATH so the tap device can not be created.
