virtio-fs with DAX is currently not compatible with NIC Pass through.
When a SR-IOV VF attaches to a qemu process, vfio will try to pin the entire 
DAX Window but it is empty when the guest boots and will fail.
A method to make VFIO and DAX to work together is to make vfio skip DAX cache.
Currently DAX cache need to be set to 0, for the SR-IOV VF to be attached to 
Kata containers.
Enabling both SR-IOV VF and DAX work together will potentially improve 
performance for workloads which are I/O and network intensive
