docker-gui's Issues

A discussion on the topic of multi-channel access

Hello, set by the object of this topic, we realized the docker Shared local resources to display in the browser desktop, also my idea is that if a server hang up multiple video CARDS, if we use our existing method, may be no matter how many users, they are all Shared a channel graphics card, other graphics in a spare, this is due to the docker remote desktop, it USES xorg Shared a physical host, so if you want to realize my this kind of multi-channel, more video card this way, continue to use the docker is not feasible?Is OpenStack a better implementation, or is VMare a better one?
