--------------------------------------------------------

Yes, when starting agent: {{./bin/mesos\-agent.sh \-\-master=127.0.0.1:5050 
--work_dir=/var/lib/mesos/agent \-\-isolation=gpu/nvidia}} , 
but appears {{Failed to create a containerizer: Could not create 
MesosContainerizer: Failed to create isolator 'gpu/nvidia': The 
'cgroups/devices' isolator must be enabled in order to use the gpu/devices 
isolator}}, 
if i want to enable {{cgroups/devices}}, from explanation of the flag 
{{\-\-isolation}}, i should {{configure with flag: 
`\-\-enable\-nvidia\-gpu\-support` to enable}}, but 
{{\-\-enable-nvidia-gpu-support}} has been removed in Mesos-5630 and can enable 
this support for all bulds on Linux, That's right?

>             Project: Mesos
>          Issue Type: Bug
>         Environment: RHEL 7.2
>            Reporter: Sunzhe
>              Labels: gpu
>             Fix For: 1.0.0

> Prerequisite: In MESOS\-5257  "By default, with no '\-\-nvidia_gpu_devices' 
> flag or `gpus` resources flag, the new auto-discovery will simply enumerate 
> all of the GPUs on the system" and in MESOS\-5630 "removes this 
> flag(\-\-enable-nvidia-gpu-support) and enables this support for all builds 
> on Linux."
> So, I '../configure' without any flag, and start agent without 
> '\-\-resources' or '\-\-nvidia_gpu_devices' ,  but can not discovery GPU 
> resources, and I also start agent with '\-\-resources' and 
> '\-\-nvidia_gpu_devices' , it also does not work.
> I'm sure the NVIDIA GPUs on my machines are OK, because with 
> '\-\-enable-nvidia-gpu-support' when './configure' and with '\-\-resources', 
> '\-\-nvidia_gpu_devices' when starting agents it works well.
