# Test Parameters:
# OPENBMC_HOST        The BMC host name or IP address.
# OS_HOST             The OS host name or IP Address.
# OS_USERNAME         The OS login userid (usually root).
# OS_PASSWORD         The password for the OS login.
# HTX_DURATION        Duration of HTX run, for example, 2h, or 30m.
# HTX_LOOP            The number of times to loop HTX.
# HTX_INTERVAL        The time delay between consecutive checks of HTX
#                     status, for example, 15m.
#                     In summary: Run HTX for $HTX_DURATION, looping
#                     $HTX_LOOP times checking for errors every $HTX_INTERVAL.
#                     Then allow extra time for OS Boot, HTX startup, shutdown.
# HTX_KEEP_RUNNING    If set to 1, this indicates that the HTX is to
#                     continue running after an error was found.
# CHECK_INVENTORY     If set to 0 or False, OS inventory checking before
#                     and after each HTX run will be disabled.  This
#                     parameter is optional.  The default value is True.
# PREV_INV_FILE_PATH  The file path and name of an initial previous
#                     inventory snapshot file in JSON format.  Inventory
#                     snapshots taken before and after each HTX run will
#                     be compared to this file.
#                     This parameter is optional.  If not specified an
#                     initial inventory snapshot will be taken before
#                     HTX startup.
# INV_IGNORE_LIST     A comma-delimited list of strings that
#                     indicate what to ignore if there are inventory
#                     differences, (e.g., processor "size").
#                     If differences are found during inventory checking
#                     and those items are in this list, the
#                     differences will be ignored.  This parameter is
#                     optional.  If not specified the default value is
#                     "size".
