Better performance (QEMU has access to your workstation CPU and memory).No waiting to write an image to an SD card.No fiddling with cables or memory cards to run on a device.What are the advantages of using QEMU instead of a device? The Mender Debian based build environment will be used as a basis for this tutorial. The article will go through both advantages and disadvantages when using a QEMU Virtual Machine instead of a real device. The goal is to enable rapid development, and the target audience is developers, with a focus on ease of use. This article will be a step-by-step tutorial on how to do virtual Mender deployments using the QEMU virtualized environment, as an alternative to using an actual x86 device. Running on real devices can often be tedious, time consuming and in some cases may be impractical. But that does not mean that development and testing necessarily has to happen this way. Before shipping software for embedded devices, it is crucial to test it on real devices, in an environment as close to the actual operating environment as possible.
