Hello,
We are trying to implement GPU-P with NVIDIA A16 cards in our Hyper-V 2025 cluster. GPU-P generally works and licenses are obtained from the cloud. However, we cannot move VMs with a GPU partition, the live migration aborts immediately.
We are using the driver package “NVIDIA-GRID-Windows_Server_Host-595.71.05-596.38-596.36” on both the host and the VM. As I understand, vGPU version 18 should support live migration. This package corresponds to vGPU version 20.1.
What can I do to resolve this issue and successfully migrate my VMs?

Please let me know what steps I can take to enable live migration for VMs with GPU-P partitions.
Thank you.
