In the following gist I'm going to guide you through the process of installing and booting an entire linux distribution with full desktop environment just like you would have with a classical VM, but with much better performance and much worse isolation :)

The reason why I did this was mainly because it's cool, but also to test new distros with decent graphics performance without actually booting them on my PC.

If you "try this at home" just keep in mind a container is not as secure as a VM, and some of the option we're going to explore will weaken container isolation from "a bit risky" to "totally unsafe" depending on what you choose.

Also, we're going to use systemd-nspawn for containers as it's probably the best fit for our use case and can also boot any linux partition without needing to prepare an apposite container image.

Less go!

Build FFmpeg and libva with decode and encode hardware acceleration on an Intel-based validation testbed:

Build platform: Ubuntu

Install baseline dependencies first

sudo apt-get -y install autoconf automake build-essential libass-dev libtool pkg-config texinfo zlib1g-dev libva-dev cmake mercurial libdrm-dev libvorbis-dev libogg-dev git libx11-dev libperl-dev libpciaccess-dev libpciaccess0 xorg-dev

Then add the Oibaf PPA, needed to install the latest development headers for libva:
