Bug Description
Mir GL clients never appear at all on VirtualBox.
After digging for a while, it appears the issue is that vboxvideo does not support DRM_CAP_PRIME and so only supports GEM flink names. Sadly Mir is the opposite now: Mir only supports PRIME but not flink names.
Internally some exceptions are being thrown in Mir at present, but we seem to catch and silence them all. So you never see any error messages at all. Just Mir GL clients never appear on screen in VirtualBox.
For the record, Wayland supports falling back to flink names in the absence of PRIME. We should too.
