• A VM using the same GPU created from the vSphere Client can be powered on.
  
  

Environment

VCF Automation 9.0

Cause

This issue occurs when the VM class used to create a VM is not reserved.

Steps to Check VM Class Reservation :

1. Connect to vCenter Server via SSH as the root user.
   If you see the prompt "Command>", type shell to access the bash shell.
   
   
   
2. Retrieve the supervisor ID by running:
   
   

   dcli com vmware vcenter namespacemanagement supervisors summary list

   
   
   
3. Use the retrieved supervisor ID to check the VM class reservation with this command:
   
   

   dcli com vmware vcenter namespacemanagement supervisors zones bindings list --supervisor <supervisor id>

   zones:
     - zone: <zone id>
       marked_for_removal: False
       resource_allocation:
         vm_reservations:  # <--- Check if reservations exist under here

    

Resolution

VM Class reservation is required to power on a VM with vGPU.

Please refer to the following document for instructions on reserving a VM class:
