[$] A QEMU case study in grappling with software complexity

There are many barriers to producing software that is reliable andmaintainable over the long term. One of those is software complexity. Atthe recently concluded 2021 KVMForum, Paolo Bonziniexploredthis topic, using QEMU, the open source emulatorand virtualizer, as a case study. Drawing on his experience asa maintainer of several QEMU subsystems, he made some concretesuggestions on how to defend against undesirable complexity. Bonziniused QEMU as a running example throughout the talk, hoping to make iteasier for future contributors to modify QEMU. However, thelessons he shared are equally applicable to many other projects.
