@deftypevr {@code{libvirt-configuration} parameter} integer keepalive-interval
A keepalive message is sent to a client after @code{keepalive_interval}
seconds of inactivity to check if the client is still responding.  If
set to -1, libvirtd will never send keepalive requests; however clients
can still send them and the daemon will send responses.

@end deftypevr

@deftypevr {@code{libvirt-configuration} parameter} integer keepalive-count
Maximum number of keepalive 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 @code{keepalive_interval * (keepalive_count + 1)} seconds since
the last message received from the client.  When @code{keepalive-count}
is set to 0, connections will be automatically closed after
@code{keepalive-interval} seconds of inactivity without sending any
keepalive messages.

@subsubheading Virtlog daemon
The virtlogd service is a server side daemon component of libvirt that is
used to manage logs from virtual machine consoles.

This daemon is not used directly by libvirt client applications, rather it
is called on their behalf by @code{libvirtd}. By maintaining the logs in a
standalone daemon, the main @code{libvirtd} daemon can be restarted without
risk of losing logs. The @code{virtlogd} daemon has the ability to re-exec()
itself upon receiving @code{SIGUSR1}, to allow live upgrades without downtime.

@deffn {Scheme Variable} virtlog-service-type
This is the type of the virtlog daemon.
Its value must be a @code{virtlog-configuration}.

@example
(service virtlog-service-type
         (virtlog-configuration
          (max-clients 1000)))
@end example
@end deffn

@deftypevr {@code{virtlog-configuration} parameter} integer log-level
Logging level.  4 errors, 3 warnings, 2 information, 1 debug.

Defaults to @samp{3}.

@end deftypevr

@deftypevr {@code{virtlog-configuration} parameter} string log-filters
Logging filters.

A filter allows to select a different logging level for a given category
of logs The format for a filter is one of:

@itemize @bullet
@item
x:name

@item
x:+name

@end itemize

where @code{name} is a string which is matched against the category
given in the @code{VIR_LOG_INIT()} at the top of each libvirt source
file, e.g., "remote", "qemu", or "util.json" (the name in the filter can
be a substring of the full category name, in order to match multiple
similar categories), the optional "+" prefix tells libvirt to log stack
trace for each message matching name, and @code{x} is the minimal level
where matching messages should be logged:

@itemize @bullet
@item
1: DEBUG

@item
2: INFO

@item
3: WARNING

@item
4: ERROR

@end itemize

Multiple filters can be defined in a single filters statement, they just
need to be separated by spaces.

Defaults to @samp{"3:remote 4:event"}.

@end deftypevr

@deftypevr {@code{virtlog-configuration} parameter} string log-outputs
Logging outputs.

An output is one of the places to save logging information The format
for an output can be:

@table @code
@item x:stderr
output goes to stderr

@item x:syslog:name
use syslog for the output and use the given name as the ident

@item x:file:file_path
output to a file, with the given filepath

@item x:journald
output to journald logging system

@end table

In all case the x prefix is the minimal level, acting as a filter

@itemize @bullet
@item
1: DEBUG

@item
2: INFO

@item
3: WARNING

@item
4: ERROR

@end itemize

Multiple outputs can be defined, they just need to be separated by
spaces.

Defaults to @samp{"3:stderr"}.

@end deftypevr

@deftypevr {@code{virtlog-configuration} parameter} integer max-clients
Maximum number of concurrent client connections to allow over all
sockets combined.

Defaults to @samp{1024}.

@end deftypevr

@deftypevr {@code{virtlog-configuration} parameter} integer max-backups
Maximum number of backup files to keep.

Defaults to @samp{3}

@end deftypevr

@subsubheading Transparent Emulation with QEMU

@cindex emulation
@cindex @code{binfmt_misc}
@code{qemu-binfmt-service-type} provides support for transparent
emulation of program binaries built for different architectures---e.g.,
it allows you to transparently execute an ARMv7 program on an x86_64
machine.  It achieves this by combining the @uref{https://www.qemu.org,
QEMU} emulator and the @code{binfmt_misc} feature of the kernel Linux.

@defvr {Scheme Variable} qemu-binfmt-service-type
This is the type of the QEMU/binfmt service for transparent emulation.
Its value must be a @code{qemu-binfmt-configuration} object, which
specifies the QEMU package to use as well as the architecture we want to
emulated:

@example
(service qemu-binfmt-service-type
         (qemu-binfmt-configuration
           (platforms (lookup-qemu-platforms "arm" "aarch64" "ppc"))))
@end example

In this example, we enable transparent emulation for the ARM and aarch64
platforms.  Running @code{herd stop qemu-binfmt} turns it off, and
running @code{herd start qemu-binfmt} turns it back on (@pxref{Invoking
herd, the @command{herd} command,, shepherd, The GNU Shepherd Manual}).
@end defvr

@deftp {Data Type} qemu-binfmt-configuration
This is the configuration for the @code{qemu-binfmt} service.

@table @asis
@item @code{platforms} (default: @code{'()})
The list of emulated QEMU platforms.  Each item must be a @dfn{platform
object} as returned by @code{lookup-qemu-platforms} (see below).

@item @code{guix-support?} (default: @code{#f})
When it is true, QEMU and all its dependencies are added to the build
environment of @command{guix-daemon} (@pxref{Invoking guix-daemon,
@code{--chroot-directory} option}).  This allows the @code{binfmt_misc}
handlers to be used within the build environment, which in turn means
that you can transparently build programs for another architecture.

For example, let's suppose you're on an x86_64 machine and you have this
service:

@example
(service qemu-binfmt-service-type
         (qemu-binfmt-configuration
           (platforms (lookup-qemu-platforms "arm"))
           (guix-support? #t)))
@end example

You can run:

@example
guix build -s armhf-linux inkscape
@end example

@noindent
and it will build Inkscape for ARMv7 @emph{as if it were a native
build}, transparently using QEMU to emulate the ARMv7 CPU.  Pretty handy
if you'd like to test a package build for an architecture you don't have
access to!

@item @code{qemu} (default: @code{qemu})
The QEMU package to use.
@end table
@end deftp

@deffn {Scheme Procedure} lookup-qemu-platforms @var{platforms}@dots{}
Return the list of QEMU platform objects corresponding to
@var{platforms}@dots{}.  @var{platforms} must be a list of strings
corresponding to platform names, such as @code{"arm"}, @code{"sparc"},
@code{"mips64el"}, and so on.
@end deffn

@deffn {Scheme Procedure} qemu-platform? @var{obj}
Return true if @var{obj} is a platform object.
@end deffn

@deffn {Scheme Procedure} qemu-platform-name @var{platform}
Return the name of @var{platform}---a string such as @code{"arm"}.
@end deffn

@node Version Control Services
@subsubsection Version Control Services

The @code{(gnu services version-control)} module provides a service to
allow remote access to local Git repositories.  There are three options:
the @code{git-daemon-service}, which provides access to repositories via
the @code{git://} unsecured TCP-based protocol, extending the
@code{nginx} web server to proxy some requests to
@code{git-http-backend}, or providing a web interface with
@code{cgit-service-type}.

@deffn {Scheme Procedure} git-daemon-service [#:config (git-daemon-configuration)]

Return a service that runs @command{git daemon}, a simple TCP server to
expose repositories over the Git protocol for anonymous access.

The optional @var{config} argument should be a
@code{<git-daemon-configuration>} object, by default it allows read-only
access to exported@footnote{By creating the magic file
"git-daemon-export-ok" in the repository directory.} repositories under
@file{/srv/git}.

@end deffn

@deftp {Data Type} git-daemon-configuration
Data type representing the configuration for @code{git-daemon-service}.

@table @asis
@item @code{package} (default: @var{git})
Package object of the Git distributed version control system.

@item @code{export-all?} (default: @var{#f})
Whether to allow access for all Git repositories, even if they do not
have the @file{git-daemon-export-ok} file.

@item @code{base-path} (default: @file{/srv/git})
Whether to remap all the path requests as relative to the given path.
If you run git daemon with @var{(base-path "/srv/git")} on example.com,
then if you later try to pull @code{git://example.com/hello.git}, git
daemon will interpret the path as @code{/srv/git/hello.git}.

@item @code{user-path} (default: @var{#f})
Whether to allow @code{~user} notation to be used in requests.  When
specified with empty string, requests to @code{git://host/~alice/foo} is
taken as a request to access @code{foo} repository in the home directory
of user @code{alice}.  If @var{(user-path "path")} is specified, the
same request is taken as a request to access @code{path/foo} repository
in the home directory of user @code{alice}.

@item @code{listen} (default: @var{'()})
Whether to listen on specific IP addresses or hostnames, defaults to
all.

@item @code{port} (default: @var{#f})
Whether to listen on an alternative port, which defaults to 9418.

@item @code{whitelist} (default: @var{'()})
If not empty, only allow access to this list of directories.

@item @code{extra-options} (default: @var{'()})
Extra options will be passed to @code{git daemon}, please run
@command{man git-daemon} for more information.

@end table
@end deftp

The @code{git://} protocol lacks authentication.  When you pull from a
repository fetched via @code{git://}, you don't know that the data you
receive was modified is really coming from the specified host, and you
have your connection is subject to eavesdropping.  It's better to use an
authenticated and encrypted transport, such as @code{https}.  Although Git allows you
to serve repositories using unsophisticated file-based web servers,
there is a faster protocol implemented by the @code{git-http-backend}
program.  This program is the back-end of a proper Git web service.  It
is designed to sit behind a FastCGI proxy.  @xref{Web Services}, for more
on running the necessary @code{fcgiwrap} daemon.

Guix has a separate configuration data type for serving Git repositories
over HTTP.

@deftp {Data Type} git-http-configuration
Data type representing the configuration for @code{git-http-service}.

@table @asis
@item @code{package} (default: @var{git})
Package object of the Git distributed version control system.

@item @code{git-root} (default: @file{/srv/git})
Directory containing the Git repositories to expose to the world.

@item @code{export-all?} (default: @var{#f})
Whether to expose access for all Git repositories in @var{git-root},
even if they do not have the @file{git-daemon-export-ok} file.

@item @code{uri-path} (default: @file{/git/})
Path prefix for Git access.  With the default @code{/git/} prefix, this
will map @code{http://@var{server}/git/@var{repo}.git} to
@code{/srv/git/@var{repo}.git}.  Requests whose URI paths do not begin
with this prefix are not passed on to this Git instance.

@item @code{fcgiwrap-socket} (default: @code{127.0.0.1:9000})
The socket on which the @code{fcgiwrap} daemon is listening.  @xref{Web
Services}.
@end table
@end deftp

There is no @code{git-http-service-type}, currently; instead you can
create an @code{nginx-location-configuration} from a
@code{git-http-configuration} and then add that location to a web
server.

@deffn {Scheme Procedure} git-http-nginx-location-configuration @
       [config=(git-http-configuration)]
Compute an @code{nginx-location-configuration} that corresponds to the
given Git http configuration.  An example nginx service definition to
serve the default @file{/srv/git} over HTTPS might be:

@example
(service nginx-service-type
         (nginx-configuration
          (server-blocks
           (list
            (nginx-server-configuration
             (listen '("443 ssl"))
             (server-name "git.my-host.org")
             (ssl-certificate
              "/etc/letsencrypt/live/git.my-host.org/fullchain.pem")
             (ssl-certificate-key
              "/etc/letsencrypt/live/git.my-host.org/privkey.pem")
             (locations
              (list
               (git-http-nginx-location-configuration
                (git-http-configuration (uri-path "/"))))))))))
@end example

This example assumes that you are using Let's Encrypt to get your TLS
certificate.  @xref{Certificate Services}.  The default @code{certbot}
service will redirect all HTTP traffic on @code{git.my-host.org} to
HTTPS.  You will also need to add an @code{fcgiwrap} proxy to your
system services.  @xref{Web Services}.
@end deffn
