GRID K2 with vDGA, Xorg not Running
Hi community, I'm working with a NVIDIA GRID K2 card, the server (small) configuration is: Server HP ML 350 (Matrox internal gpu included) 1 Xeon 6 core 500 HDD 16 GB RAM 1 NVIDIA GRID K2 The hypervisor is vmware ESXi 6 U2. Now is configured with passthrough (2 virtual machines added as PCI devices), but the Xorg is not running in the server (ML 350). Is that ok? The nvidia-smi works in the virtual machines. But in the server is doesnt work. Also vib is installed (in the server) but I think it doesnt matter. Thanks,
Hi community,

I'm working with a NVIDIA GRID K2 card, the server (small) configuration is:

Server HP ML 350 (Matrox internal gpu included)
1 Xeon 6 core
500 HDD
16 GB RAM
1 NVIDIA GRID K2

The hypervisor is vmware ESXi 6 U2.

Now is configured with passthrough (2 virtual machines added as PCI devices), but the Xorg is not running in the server (ML 350).

Is that ok?

The nvidia-smi works in the virtual machines. But in the server is doesnt work. Also vib is installed (in the server) but I think it doesnt matter.

Thanks,

Hi If you're running in Passthrough, there's no point in installing the .vib in the Hypervisor as it won't do anything. This will be why it's working. If you were to try a vGPU Profile, you [i]may[/i] have issues starting the VM. As for SMI, this is expected, as you are not using any vGPUs so the Hypervisor can't query them. Monitoring SMI within each VM will be your only option in this configuration. Regards Ben

Hi Thank you Ben. My virtual machine (Ubuntu) is working with the nvidia driver vDGA. I don't want to use the vGPU profile because it doesn't support Linux (GRID K2). But, is necessary that Xorg is running on the server? Also, with vmware Which remote protocol should I use for vDGA? VMware Blast or PCoIP?? Thanks,

No, Xorg isn't required for Passthrough. The Hypervisor isn't doing anything with the GPU other than attaching it to your VMs. Whether you're using vGPU or Passthrough, the choice in protocol should be based on what you plan to deliver, not the GPU Profile. Ideally, your delivery technology will have a multi-codec protocol. This will give you the most flexibility. Regards

Thanks for the answers, now, Which 3D renderer should use for Linux desktop pool with vDGA? (Manage using vsphere Client, Automatic, Hardware, Software, vGPU or disabled)

The VMware documentation is very good. So refer to that for the specifics. https://pubs.vmware.com/horizon-7-view/index.jsp#com.vmware.horizon-view.linuxdesktops.doc/GUID-D4A8AD5E-15C1-40D5-B471-D9797BEC49AB.html
