From inside virutal machine how to check if the VF(Virtual Function) is on which numa node ?

Issue

• VFs (Virtual Function) has been presented to VM, now from inside VM how to check if the VF is on which numa node ? The output of /sys/class/pci_bus/0000\:00/device/<bus-of-VF>/numa_node OR /sys/class/net/<VF-interface-name>/device/numa_node shows -1
• There is a application running on guest/VM which needs this information to be fetched from VM itself so that it can work optimally.
