TL; DR: Can I configure a container to access natively the VGA, overriding the host video output?
I'm thinking about disposing of my low-power XenServer (previously ESXi) whitebox to setup a docker minimal installation (e.g. CoreOS, RancherOs or a similar distribution). Would it be possible to give a (possibly not privileged) container exclusive access/passthrough to the video output, to install a media center solution (e.g. Kodi) that could run together with all the other containers, with a fullscreen video output to a TV, "obviously" with hardware accelerated video decoding?
I'm trying to move between --privileged, --device, -v /dev/vga?:.... but I have to admin I'm quite new to this and the only informations I could find were related to USB or CUDA: similar, but not exactly the same thing.
TIA
With a little bit of pain you will be able to configure minimal install of xserver and video drivers on host, and after that with a little bit of pain configure container to use passed x11 socket from host machine.
