It seems that the function uuid_to_vmid [in src/utils](https://github.com/mbilker/vgpu_unlock-rs/blob/master/src/utils.rs#L38) has some problems.
// Ensure that the first parts of the uuid are only 0
if uuid.0 != 0 || uuid.1 != 0 || uuid.2 != 0 || uuid.3[0] != 0 || uuid.3[1] != 0 {
return None;
}
The first block should be the vm PCIE number.. Refer. https://forum.proxmox.com/threads/automatically-assign-uuid-to-a-vgpu-instance.98994/post-427480
