Update existing vGPU environment

If an existing GRID Virtual GPU Manager is already installed on the system and you wish to upgrade, follow these steps:

  • Shut down any VMs that are using GRID vGPU.
  • Download NVIDIA GRID vGPU driver from and unpackage the zip folder. Look for the NVIDIA-vgx-xenserver-6.2-331.59.i386.rpm file
    Use WinSCP and connect to your XenServer and transfer the file
  • Install the new package using the –Uv option to the rpm command, to upgrade from the previously installed package: 
    rpm -Uv NVIDIA-vgx-xenserver-6.2-331.59.i386.rpm
    FYI – You can use XenCenter CLI or Putty to execute above command
  • Reboot XenServer host
  • Install XenServer hotfix XS62ESP1004 to the host and reboot
    * Use CTX132791 for further info how to update a XenServer single host or Pool
  • Now you can see the new vGPU profile in XenCenter and XenDesktop Studio.
  • On all your vGPU virtual machines, update the NVIDIA Windows drivers for vGPU, version 332.83
Note: the GRID vGPU Manager and Windows guest VM drivers must be installed together. Older VM drivers will not function correctly with this release of GRID vGPU Manager. Similarly, older GRID vGPU Managers will not function correctly with this release of Windows guest drivers
GRID vGPU on Citrix XenServer does not support operation with physical GPUs BARs mapped above the 4 Gigabyte boundary in the system address space.Ensure that GPUs are mapped below the 4G boundary by disabling your server’s SBIOS option that controls 64-bit memory-mapped I/O support. This option may be labeled “Enable >4G Decode” or “Enable 64-bit MMIO”.
