Part3: GPU-VDI deep dive – Post install GPU driver verification

Post NVIDIA driver (VIB) installation verification
[Exit Maintenance Mode]
SSH to the ESXi host, use the command gpuvm to see if the hypervisor is able to detect the GPU memory capacity. Below is an example for your reference. If GPU memory is assigned to VMs, then the GPU maximum memory and GPU memory left values will NOT be the same. In this example, since there are not powered on VMs, therefore both the values are showing as same.
~ # gpuvm
Xserver unix:0, GPU maximum memory 2076672KB
GPU memory left 2076672KB.

Post NVIDIA GPU card & driver configuration
As soon as the View pooled desktops are online, the hypervisor automatically allocates GPU memory to each of the desktops (shown below). Based on the View pool settings (as shown below) the hypervisor uses memory either from CPU (software), GPU (hardware) or VMware software (using vSphere client)

From the ESXi console (SSH):
~ # gpuvm
Xserver unix:0, GPU maximum memory 2076672KB
pid 24686, VM “viewfltg1”, reserved 131072KB of GPU memory.
pid 24720, VM “viewfltg4”, reserved 131072KB of GPU memory.
pid 24691, VM “viewfltg2”, reserved 131072KB of GPU memory.
pid 24692, VM “viewfltg3”, reserved 131072KB of GPU memory.
pid 25919, VM “viewfltg7”, reserved 131072KB of GPU memory.
pid 25920, VM “viewfltg8”, reserved 131072KB of GPU memory.
pid 25674, VM “viewfltg5”, reserved 131072KB of GPU memory.
pid 25675, VM “viewfltg6”, reserved 131072KB of GPU memory.
pid 52907, VM “viewfltg9”, reserved 131072KB of GPU memory.
pid 53146, VM “viewfltg10”, reserved 131072KB of GPU memory.
GPU memory left 765952KB.

About cloudray

Predominantly based around Virtualization, but will include other technology related information and anything else I find interesting and feel the need to share with you. I also use this Blog as both a place to store useful information that I think that will come in handy to me at some point in the future, and also a place to help aid my learning. I find a great way to learn about something is to research about it and then write it up in my own words. I'm Pushpal Ray, from India. As a certified VCP3/4/5 professional, I am currently working as an Independent Consultant. Over 10 years of IT-industry experience, currently focused around the Desktop Virtualization(End-User Computing). I also have extensive experience in Windows Administration, Datacenter Migration, Workload profiling & benchmarking. At my leisure, I enjoy hiking, running, photography, spend hours in my fav coffee shop & spend quality time with my wife. Occasionally, catch up with few friends for a drink!
