Additional topics available exclusively in classroom settings (note: only brief descriptions, not live demonstrations, are provided for remote courses):

  • Running Mac OS X on KVM (requires at least one participant with a Mac running Linux)
  • 3D graphics acceleration with VirGL
  • 3D graphics with Intel GPUs (specifically Broadwell, Skylake, or early Kaby Lake families, i.e., 5th–7th generation; later models are not supported) using igvtg, or the equivalent "mediated passthrough" for NVIDIA Quadro and Tesla cards
  • Video card passthrough (requires a desktop with two video cards, preferably AMD)
  • USB device passthrough

Requirements

Proficiency in general Linux command-line operations and working knowledge of TCP/IP networks
