+# Purposes of the following whitelist:
+# * Avoiding verbose log messages when we find known non-fatal
+# (exitcode=1) errors
+# * Avoiding fatal errors when we find known crashes
+# * Skipping machines/devices that are known not to work out of
+# the box, when running in --quick mode
+#
+# Keeping the whitelist updated is desirable, but not required,
+# because unexpected cases where QEMU exits with exitcode=1 will
+# just trigger a INFO message.
+
+# Valid whitelist entry keys:
+# * accel: regexp, full match only
+# * machine: regexp, full match only
+# * device: regexp, full match only
+# * log: regexp, partial match allowed
+# * exitcode: if not present, defaults to 1. If None, matches any exitcode
+# * warn: if True, matching failures will be logged as warnings
+# * expected: if True, QEMU is expected to always fail every time
+# when testing the corresponding test case
+# * loglevel: log level of log output when there's a match.
