hw_hotplug job would most of the time throw errors on one of device removals, while running with vfio-pci driver. This issue was not present for uio_pci_generic driver. The hw_hotplug.sh script would detect "Starting I/O..." log, before "Initializing NVMe Controllers" in function register_controllers() was printed. This indicates that the log.txt contained logs from previous hw_hotplug test.
