Then:

# cd ..
# hob

Now an instance of Hob (the GTK2-based graphical user intece for BitBake) should start, checking for the correctness of build system.

Now select qemux86 as machine in the dropdown menu.

Wait until Hob will finish parsing BitBake recipes and generating dependency tree. Then, select your preferred target image to build from the "select an image recipe" from the menu above. In this sample we'll select the full core image without the GUI: core-image-full-cmdline.

Now click on "Advanced Configuration".

In "Image types" panel leave poky in the "Distro" menu if you want to build the latest stable release. Then in "Image types" field select the format you need: usually, I select ".iso", ".vdi" and ".vmdk", they are the most useful and comfortable formats.

In "Output" panel please select the best options that fit your needs. I suggest to add at least 4GB of free storage to your image, to populate the SDK for i686 architecture (if you are playing with Edison development board). In addition, I find very usefull to set "deb" as packaging format for the root filesystem. So, as follows:

Ok, save. Now, you are ready to build your image! Click on "Build image" button!

Hob will launch for you an instance of bitbake core-image-full-cmdline with your favorite settings.

Note 7: this process will take a very long time to build the final images. But depending on your host machine capabilities you can change the number of processor cores used in build operation acting on "BitBake parallel threads" and "Make parallel threads". To can modify these variables from Hob settings window:
