In this section you will review what a vGPU profile is, considerations when selecting a profile, and modifying a profile. You will
1. Define a virtual graphics process unit (vGPU) Profile
2. Set and Modify a vGPU Profile
This part of the lab is presented as a Hands-on Labs Interactive Simulation. This will allow you to experience steps which are too time-consuming or resource intensive to do live in the lab environment. In this simulation, you can use the software interface as if you are interacting with a live environment.
The orange boxes show where to click, and the left and right arrow keys can also be used to move through the simulation in either direction.
A vGPU profile allows you to assign specific amounts of GPU resources to a VM. Providing the ability for multiple desktops to access the same GPU, while insuring that there are enough resources available to handle the expected graphics load. Identifying user needs and requirements are essential to a positive user experience. Once the user requirements have been defined, you can easily map the vGPU profile.
Typically shared-pass through cards support a variety of GPU profiles. In this lab we will be using the NVIDIA Tesla M60. Profiles range from the M60-0q which is comprised of 512M of GPU memory and 16 vGPU per GPU to the M60-8q that includes 8G of GPU memory and 1 vGPU. Each shared-pass through card (vGPU) located on our compatibility guide supports a variety of vGPU profiles depending on the features and functionality available on said card.
GPU hardware manufacturers often assign a recommended use case for a particular vGPU profile. Though these recommendations can be a great starting point, there are some additional considerations you should make before selecting a profile for your use case.
One of the first places you can start, is to assess the principal applications that will be used within the virtual desktop. Taking into account the application requirements set by the applications vendor, helps to ensure the application is being provided enough resources to work as expected.
Next you will want to ask some additional questions, for example:
Regardless of what profile you chose to use, be sure to test it before deploying it to your end users to confirm the user experience is working as expected.
The vGPU is added to a VM by adding it as a PCI device. The vGPU profile is selected during this process.
The current profile is set to grid-m60-0q.
Notice how the GPU Profile is grayed out. This is due to the fact that the VM is powered on. A VM must be powered off, in order to modify the GPU profile.
Note: The certificate warning appears due to the fact that self signed certs are being used in the lab. VMware highly recommends replacing the self signed certs in a production environment
The NVIDIA GRID M60-0Q, is the same name as the GPU Profile that was selected when we reviewed the VM settings.
Note: The vGPU Client drivers must be installed for the guest OS to recognize the vGPU card. Details on how to do so can be found in Module 4 of this lab.
To modify the current vGPU Profile on a VM is a relatively easy process.
The display adapter now reflects the new vGPU profile. NVIDIA GRID M60-2Q
