 No. We told about "experimental" because given we didn't have a CI
verifying the features, we were not sure operators were not having a lot of
bugs. After 2 cycles, we don't have a lot of bugs and some operators use
it, so we could remove the "experimental" situation.

Make sure you use the correct grid server driver from nvidia and then
follow those steps :
https://docs.nvidia.com/grid/6.0/grid-vgpu-user-guide/index.html#install-vgpu-package-generic-linux-kvm

Once the driver will be installed (make sure tho you remove first the
nouveau driver as said above) and the system rebooted, you should see the
above sysfs directory.
