+# Logging controls
+#
+
+# Logging level: 4 errors, 3 warnings, 2 information, 1 debug
+# basically 1 will log everything possible
+#
+# WARNING: USE OF THIS IS STRONGLY DISCOURAGED.
+#
+# WARNING: It outputs too much information to practically read.
+# WARNING: The "log_filters" setting is recommended instead.
+#
+# WARNING: Journald applies rate limiting of messages and so libvirt
+# WARNING: will limit "log_level" to only allow values 3 or 4 if
+# WARNING: journald is the current output.
+#
+# WARNING: USE OF THIS IS STRONGLY DISCOURAGED.
+#log_level = 3
+
+# Logging filters:
+# A filter allows to select a different logging level for a given category
+# of logs. The format for a filter is:
+#
+#    level:match
+#
+# where 'match' is a string which is matched against the category
+# given in the VIR_LOG_INIT() at the top of each libvirt source
+# file, e.g., "remote", "qemu", or "util.json". The 'match' in the
+# filter matches using shell wildcard syntax (see 'man glob(7)').
+# The 'match' is always treated as a substring match. IOW a match
+# string 'foo' is equivalent to '*foo*'.
+#
+# 'level' 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 @log_filters, they just need
+# to be separated by spaces. Note that libvirt performs "first" match, i.e.
+# if there are concurrent filters, the first one that matches will be applied,
+# given the order in @log_filters.
+#
+# For the virtlogd daemon, a typical need is to capture information
+# from the logging code and some of the utility code. Some utility
+# code is very verbose and is generally not desired. A suitable filter
+# string for debugging might be to turn off object, json & event logging,
+# but enable the rest of the util and the logging code:
+#
+#log_filters="1:logging 4:object 4:json 4:event 1:util"
+
+# Logging outputs:
+# An output is one of the places to save logging information
+# The format for an output can be:
+#    level:stderr
+#      output goes to stderr
+#    level:syslog:name
+#      use syslog for the output and use the given name as the ident
+#    level:file:file_path
+#      output to a file, with the given filepath
+#    level:journald
+#      output to journald logging system
+# In all cases 'level' is the minimal priority, acting as a filter
+#    1: DEBUG
+#    2: INFO
+#    3: WARNING
+#    4: ERROR
+#
+# Multiple outputs can be defined, they just need to be separated by spaces.
+# e.g. to log all warnings and errors to syslog under the virtlogd ident:
+#log_outputs="3:syslog:virtlogd"
+#
+
+# The maximum number of concurrent client connections to allow
+# on primary socket
+#max_clients = 1024
+
+# The maximum number of concurrent client connections to allow
+# on administrative socket
+#admin_max_clients = 5
+
+# Maximum file size before rolling over. Defaults to 2 MB
+#
+# Setting max_size to zero will disable rollover entirely.
+# NOTE: disabling rollover exposes the host filesystem to
+# denial of service from a malicious guest.
+#
+# Beware that a logrotate config file might be installed too,
+# to handle cases where virtlogd is disabled. To ensure that
+# the logrotate config is a no-op when virtlogd is running,
+# make sure that max_size here is smaller than size listed
+# in the logrotate config.
+#max_size = 2097152
+
+# Maximum number of backup files to keep. Defaults to 3,
+# not including the primary active file
+#max_backups = 3
+
+# Maximum age for log files to live after the last modification.
+# Defaults to 0, which means "forever".
+#
+# WARNING: since virtlogd has no way to differentiate which files it used to
+# manage, the garbage collection mechanism will collect ALL files, once its age
+# reach max_age_days. Use only if you know what you mean.
+#max_age_days = 0
