When you imported the virtual machine you might have changed the number of processors made available to the virtual machine itself. If you did that, you can optimize the build time in this way:
This modification will be available just for the current build directory, to make it permanent please refer to Poky’s guide on How to speedup the build process.
It is possible to choose between the following formats:
by clicking on Settings → Output
choosing your preferred package format, and saving.
Select pengwyn from the combo-box, after the recipes have been parsed the section Select a base image will appear and you can choose your preferred image.
Click on Build image
than the build process will start.
Please note that the build process can last several hours till it finishes.
It might happen that a fetch task gives an error, if so, double check that the virtual machine has a proper network configuration. If the network configuration has been proved correct, the error might mean that the needed server is down for some reason, in that case the only option you have is to wait and try again later.
There are two possible ways to customize an image to build:
Once you selected a predefined image, you can click on View recipes to add/remove recipes and tasks or you can click on View packages to add/remove previously built packages. After the image has been customized you can build your image. If you want to customize every detail you can choose Create your own image from the drop down menu of section Select a base image, than, as previously stated, you can customize the content of your file system and build it.
