Dear StarlingX community, We are attempting to configure VGPU sharing via MIG (Multi-Instance GPU) on NVIDIA H200 cards within a StarlingX (STX) 24.09 environment running OpenStack (Caracal). Platform's configuration details: StarlingX (STX) 24.09 con OpenStack(Caracal). Hardware: GPU NVIDIA H200. CPU : AMD EPYC Kernel : vmlinuz-6.6.0-1-amd64 We successfully installed and deployed the nvidia-vgpu-ubuntu-aie-580_580.82.0.deb patch on the two controllers via USM. The NVIDIA platform is functional: we were able to perform GPU segmentation using MIGs and associate these cuts with the VFs, following the official NVIDIA GRID VGPU guide (https://docs.nvidia.com/vgpu/latest/grid-vgpu-user-guide/index.html#ubuntu-i...). The GPU supports VGPU/MIG sharing via VFs (Virtual Functions) using Vendor-Specific VFIO. To enable VF sharing with OpenStack, we applied the following helm override configuration in StarlingX, updating Nova parameters based on the official OpenStack PCI Passthrough documentation (https://docs.openstack.org/nova/latest/admin/pci-passthrough.html) [cid:c38841c5-844c-487c-af80-13a805e63451] where 0000:03:00.2 it is the PCI address of a VF linked to a MIG with capacity of 7G_141. However, when we attempt to attach the VF to a Guest VM using a Nova flavour, the physical node crashes, resulting in the attached logs. Does anyone have specific experience or documentation regarding this configuration of StarlingX/OpenStack, VGPU/MIG with NVIDIA Vendor-Specific VFIO} ? Specifically, we are looking for the following: * Confirmation or correction of the Nova PCI overrides. * Guidelines/commands to correctly integrate the VGPU/MIG driver with Nova and StarlingX. * Are there any additional steps required on the system STX or OpenStack components? Note: A VM without GPU but with ethernet card shared via SRIOV works well Thank you !
