Hi,

There is a way of exposing a device to a container.
First of all, you'll need device node in /dev.
You can create it manually.
If you need sysfs layout for this, it's also possible (but a bit more tricky).
Please, note, that device access will be shared with the host. IOW, it's not bypassing, but sharing of a device and you can share it with as many virtual environments as you want.
