Placing virtual graphics processing unit (GPU)-configured virtual machines on physical GPUs supporting multiple virtual GPU profiles
In one set of embodiments, a computer system can receive a request to provision a virtual machine (VM) in a host cluster, where the VM is associated with a virtual graphics processing unit (GPU) profile indicating a desired or required framebuffer memory size of a virtual GPU of the VM. In response, the computer system can execute an algorithm that identifies, from among a plurality of physical GPUs installed in the host cluster, a physical GPU on which the VM may be placed, where the identified physical GPU has sufficient free framebuffer memory to accommodate the desired or required framebuffer memory size, and where the algorithm allows multiple VMs associated with different virtual GPU profiles to be placed on a single physical GPU in the plurality of physical GPUs. The computer system can then place the VM on the identified physical GPU.
