cannot enable webgl for chromium in virtualbox

Question

I'm trying to run webgl in chromium browser in virtualbox on Ubuntu 14.04.

First I set in chrome://settings hardware acceleration when available to checked,
then in chrome://flags I enabled everything about webgl,
but in chrome://gpu I still have status WebGL: Unavailable.
In virtualbox setting I checked 3D acceleration, not 2D acceleration.

Please, don't you have any idea how to solve it?

Answer 1

Have you tried enable the flag of ＂Override software rendering list＂ in chrome://flags, or append command line switch "--ignore-gpu-blacklist"?
