+# The format for a filter is one of:
+#    x:name
+#    x:+name
+#      where name is a string which is matched against source file name,
+#      e.g., "remote", "qemu", or "util/json", the optional "+" prefix
+#      tells libvirt to log stack trace for each message matching name,
+#      and x is the minimal level where matching messages should be logged:
+#    1: DEBUG
+#    2: INFO
+#    3: WARNING
+#    4: ERROR
+#
+# Multiple filters can be defined in a single @filters, they just need to be

+# from the event layer:
+#log_filters="3:remote 4:event"
+
+# Logging outputs:
+# An output is one of the places to save logging information
+# The format for an output can be:
+#    x:stderr
+#      output goes to stderr
+#    x:syslog:name
+#      use syslog for the output and use the given name as the ident
+#    x:file:file_path
+#      output to a file, with the given filepath
+#    x:journald
+#      output to journald logging system
+# In all case the x prefix is the minimal level, acting as a filter

+#    2: INFO
+#    3: WARNING

+# messages that are allowed to be sent to the client without getting
+# any response before the connection is considered broken.  In other
+# words, the connection is automatically closed approximately after
+# keepalive_interval * (keepalive_count + 1) seconds since the last
+# message received from the client.  If keepalive_interval is set to
+# -1, libvirtd will never send keepalive requests; however clients
