The current guest image is not prepared for Poky development because it needs the default required packages http://www.yoctoproject.org/docs/2.1/ref-manual/ref-manual.html#required-packages-for-the-host-development-system The build-appliance image can be used as a reference https://www.yoctoproject.org/tools-resources/projects/build-appliance The documentation change is inside patchtest, nothing related to the main manuals.
Fixed by http://git.yoctoproject.org/cgit/cgit.cgi/patchtest/commit/?id=85234644929d2da9178e64a80c063821970a6b87 Currently proposed patches are not reviewed outside Intel but once the system is presented to the community, these will be sent to the proper mailing list (yocto at this point)
