#
# Authentication.
#
# There are the following choices available:
#
# - none: do not perform auth checks. If you can connect to the
# socket you are allowed. This is suitable if there are
# restrictions on connecting to the socket (eg, UNIX
# socket permissions), or if there is a lower layer in
# the network providing auth (eg, TLS/x509 certificates)
#
# - sasl: use SASL infrastructure. The actual auth scheme is then
# controlled from /etc/sasl2/libvirt.conf. For the TCP
# socket only GSSAPI & DIGEST-MD5 mechanisms will be used.
# For non-TCP or TLS sockets, any scheme is allowed.
#
# - polkit: use PolicyKit to authenticate. This is only suitable
# for use on the UNIX sockets. The default policy will
# require a user to supply their own password to gain
# full read/write access (aka sudo like), while anyone
# is allowed read/only access.
#
# Set an authentication scheme for UNIX read-only sockets
#
# By default socket permissions allow anyone to connect
#
# If libvirt was compiled without support for 'polkit', then
# no access control checks are done, but libvirt still only
# allows execution of APIs which don't change state.
#
# If libvirt was compiled with support for 'polkit', then
# the libvirt socket will perform a check with polkit after
# connections. The default policy still allows any local
# user access.
#
# To restrict monitoring of domains you may wish to either
# enable 'sasl' here, or change the polkit policy definition.
#auth_unix_ro = "polkit"
# Set an authentication scheme for UNIX read-write sockets.
#
# If libvirt was compiled without support for 'polkit', then
# the systemd .socket files will use SocketMode=0600 by default
# thus only allowing root user to connect, and 'auth_unix_rw'
# will default to 'none'.
#
# If libvirt was compiled with support for 'polkit', then
# the systemd .socket files will use SocketMode=0666 which
# allows any user to connect and 'auth_unix_rw' will default
# to 'polkit'. If you disable use of 'polkit' here, then it
# is essential to change the systemd SocketMode parameter
# back to 0600, to avoid an insecure configuration.
#
#auth_unix_rw = "polkit"
# Change the authentication scheme for TCP sockets.
#
# If you don't enable SASL, then all TCP traffic is cleartext.
# Don't do this outside of a dev/test scenario. For real world
# use, always enable SASL and use the GSSAPI or DIGEST-MD5
# mechanism in /etc/sasl2/libvirt.conf
#auth_tcp = "sasl"
# Change the authentication scheme for TLS sockets.
#

# layer, and limited authentication is done by certificates
#
# It is possible to make use of any SASL authentication
# mechanism as well, by using 'sasl' for this option
#auth_tls = "none"
# Change the API access control scheme
#
# By default an authenticated user is allowed access
# to all APIs. Access drivers can place restrictions
# on this. By default the 'nop' driver is enabled,
# meaning no access control checks are done once a
# client has authenticated with libvirtd

# TLS x509 certificate configuration

# for the certificate files is as follows:

# /etc/pki/libvirt/servercert.pem - The server certificate signed by cacert.pem
# /etc/pki/libvirt/private/serverkey.pem - The server private key
#
# It is possible to override the default locations by altering the 'key_file',
# 'cert_file', and 'ca_file' values and uncommenting them below.
#
# NB, overriding the default of one location requires uncommenting and
# possibly additionally overriding the other settings.
#
# Override the default server key file path
#
#key_file = "/etc/pki/libvirt/private/serverkey.pem"

# 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.
#
# A typical need is to capture information from a hypervisor driver,
# public API entrypoints and some of the utility code. Some utility
# code is very verbose and is generally not desired. Taking the QEMU
# hypervisor as an example, a suitable filter string for debugging
# might be to turn off object, json & event logging, but enable the
# rest of the util code:
#
log_filters="1:qemu"
# 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 libvirtd ident:

# -1, libvirtd will never send keepalive requests; however clients

# Master configuration file for the QEMU driver.

# server-cert.pem - the server certificate signed with ca-cert.pem
# server-key.pem - the server private key
#
# and optionally may contain
#
# dh-params.pem - the DH params configuration file

# If the directory does not exist, libvirtd will fail to start. If the
# directory doesn't contain the necessary files, QEMU domains will fail
# to start if they are configured to use TLS.
#
# In order to overwrite the default path alter the following. This path

# allowing the client to verify the server's identity and establish
# an encrypted channel.
#
# It is possible to use x509 certificates for authentication too, by

# This configuration option is obsolete. Libvirt will follow the
# QEMU firmware metadata specification to automatically locate
# firmware images. See docs/interop/firmware.json in the QEMU
# source tree. These metadata files are distributed alongside any
# firmware images intended for use with QEMU.
#
# NOTE: if ANY firmware metadata files are detected, this setting
# will be COMPLETELY IGNORED.
#
# ------------------------------------------
#
# When a domain is configured to use UEFI instead of standard
# BIOS it may use a separate storage for UEFI variables. If
# that's the case libvirt creates the variable store per domain
# using this master file as image. Each UEFI firmware can,
# however, have different variables store. Therefore the nvram is
# a list of strings when a single item is in form of:
# ${PATH_TO_UEFI_FW}:${PATH_TO_UEFI_VARS}.
# Later, when libvirt creates per domain variable store, this list is
# searched for the master image. The UEFI firmware can be called
# differently for different guest architectures. For instance, it's OVMF
# for x86_64 and i686, but it's AAVMF for aarch64. The libvirt default
# follows this scheme.
#nvram = [
# "/usr/share/OVMF/OVMF_CODE.fd:/usr/share/OVMF/OVMF_VARS.fd",
# "/usr/share/OVMF/OVMF_CODE.secboot.fd:/usr/share/OVMF/OVMF_VARS.fd",
# "/usr/share/AAVMF/AAVMF_CODE.fd:/usr/share/AAVMF/AAVMF_VARS.fd",
# "/usr/share/AAVMF/AAVMF32_CODE.fd:/usr/share/AAVMF/AAVMF32_VARS.fd"
#]
# The backend to use for handling stdout/stderr output from
# QEMU processes.
#
# 'file': QEMU writes directly to a plain file. This is the
# historical default, but allows QEMU to inflict a
# denial of service attack on the host by exhausting
# filesystem space
#
# 'logd': QEMU writes to a pipe provided by virtlogd daemon.
# This is the current default, providing protection
# against denial of service by performing log file
# rollover when a size limit is hit.

# QEMU gluster libgfapi log level, debug levels are 0-9, with 9 being the
# most verbose, and 0 representing no debugging output.

# The current logging levels defined in the gluster GFAPI are:
#
# 0 - None
# 1 - Emergency
# 2 - Alert
# 3 - Critical
# 4 - Error
# 5 - Warning

# 7 - Info

# To enhance security, QEMU driver is capable of creating private namespaces
# for each domain started. Well, so far only "mount" namespace is supported. If
# enabled it means qemu process is unable to see all the devices on the system,
# only those configured for the domain in question. Libvirt then manages
# devices entries throughout the domain lifetime. This namespace is turned on
# by default.
#namespaces = [ "mount" ]
# This directory is used for memoryBacking source if configured as file.
# NOTE: big files will be stored here

# used whenever <reservations/> are enabled for SCSI LUN devices.

# For debugging and testing purposes it's sometimes useful to be able to disable
# libvirt behaviour based on the capabilities of the qemu process. This option
# allows to do so. DO _NOT_ use in production and beaware that the behaviour
# may change across versions.
#
#capability_filters = [ "capname" ]
# 'deprecation_behavior' setting controls how the qemu process behaves towards
# deprecated commands and arguments used by libvirt.
#
# This setting is meant for developers and CI efforts to make it obvious when
# libvirt relies on fields which are deprecated so that it can be fixes as soon
# as possible.
#
# Possible options are:
# "none" - (default) qemu is supposed to accept and output deprecated fields
# and commands
# "omit" - qemu is instructed to omit deprecated fields on output, behaviour
# towards fields and commands from qemu is not changed
# "reject" - qemu is instructed to report an error if a deprecated command or
# field is used by libvirtd
# "crash" - qemu crashes when an deprecated command or field is used by libvirtd
#
# For both "reject" and "crash" qemu is instructed to omit any deprecated fields
# on output.
#
# The "reject" option is less harsh towards the VMs but some code paths ignore
# errors reported by qemu and thus it may not be obvious that a deprecated
# command/field was used, thus it's suggested to use the "crash" option instead.
#
# In cases when qemu doesn't support configuring the behaviour this setting is
# silently ignored to allow testing older qemu versions without having to
# reconfigure libvirtd.
#
# DO NOT use in production.
#
#deprecation_behavior = "none"
