Comment 2 for bug 1366805

Apart from the strange errno in the logs above.. to allow mir to run on vbox we need to add page flipping and the default implementation of prime to the vbox drm driver:

http://www.virtualbox.org/svn/vbox/trunk/src/VBox/Additions/linux/drm/

page flipping has been adde here:

That plus mesa 10.3 and mir should work. Maybe there is also a way to use the virtualbox GL implementation?
