A while ago, I wrote about building a rack for a Raspberry Pi cluster. Now, if you have a rack, at some point you’re gonna want to put some Pis on it. Copying stock disk images onto these Pis and then configuring them by hand is a massive pain, but with virtualization you can emulate and even automate that whole process, generating custom image files from the comfort of your desktop. Here’s a quick crash course in virtualizing the Pi using QEMU.
All the guides I could find on this were at least a couple years old and were missing various important parts of the process. None of them quite worked out-of-the-box. It’s hard to blame them, though, since a hardware platform like the Pi is of course a moving target. For what it’s worth, this guide should be complete and up-to-date as of October 2016.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
