Thanks a lot for your prompt reply !

JFYI, The invalid NUma socket was resolved by manually changing the entry
to 0

echo 0 > /sys/bus/pci/devices/0000\:01\:00.0/uio/uio0/device/numa_node
echo 0 > /sys/bus/pci/devices/0000\:01\:00.1/uio/uio1/device/numa_node

Is vfio driver mandatory ? i see few error messages related to it.

Also, I see few error messages related to memory allocation, but I am not
sure how to fix this. Can you please help me out here.

Thanks,
