Overview
This practical course contains topics addressed to system administrators, developers, embedded developers and ordinary desktop users (including managers) who would like to have an introduction to virtualization in general. After this course, administrators will be able to create private clouds for use in production, and developers will be able to test their code on multiple operating systems without needing a second PC or a non-x86 board.
We understand that the set of topics presented in this course covered a wide range of subjects that might not be applicable for all customers. When booking this course, please specify what you wish to achieve using QEMU or KVM, and we will customize it by reallocating time from less relevant topics to the ones that would be important for you.
Requirements
General Linux command line skills, working TCP/IP knowledge

Bonus topics available in classroom only (i.e. only short descriptions, not demonstrations, are available in remote courses):
- Running Mac OS X in KVM (if at least one participant has a Mac with Linux installed)
- 3D graphics with VirGL
- 3D graphics with Intel GPU (must be of Broadwell, Skylake or early Kabylake family, i.e. 5th-7th generation, not later) and igvtg, or the equivalent “mediated passthrough” for NVidia Quadro and Tesla cards
- Video card passthrough (if there is a desktop available with two video cards, ideally AMD)
- USB device pass-through
