--------------------------------------------------------
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?

> Can't autodiscovery GPU resources without '--enable-nvidia-gpu-support' and
> '--nvidia_gpu_devices' flags

> Key: MESOS-5717
> URL: https://issues.apache.org/jira/browse/MESOS-5717
> 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.
