Mirage keys

val target : mode key

-t TARGET: Key setting the configuration mode for the current project. Is one of "unix", "macosx", "xen", "qubes", "virtio", "hvt" or "muen".

val pp_target : mode Fmt.t

Pretty printer for the mode.

val is_unix : bool value

Is true iff the target key is a UNIXish system ("unix" or "macosx").

val warn_error : bool key

--warn-error. Enable -warn-error for OCaml sources. Set to false by default, but might might enabled by default in later releases.

val target_debug : bool key

Enables target-specific support for debugging.

val tracing_size : int -> int key

--tracing-size: Key setting the tracing ring buffer size.

Generic keys

Some keys have a group optional argument. This group argument allows to give several keys a prefix.

For example, if we have two ip stacks, one external and one internal, We can use the group option to name them in and out. This way, the available keys will be --in-ip and --out-ip.

If a key has another, non-optional argument. It is the default value.

Keys are always named the same as their command line option.

File system keys

val kv_ro : 
  ?group:string ->
  unit ->
  [ `Archive | `Crunch | `Direct | `Fat ] key

The type of key value store. Is one of "archive", "crunch", "direct", or "fat".

val block : 
  ?group:string ->
  unit ->
  [ `XenstoreId | `BlockFile | `Ramdisk ] key

Block device keys

PRNG key

val prng : ?group:string -> unit -> [ `Stdlib | `Nocrypto ] key

The type of pseudo random number generator to use by default. Is one of "stdlib" (lagged Fibonacci), or "nocrypto" (Fortuna).

Stack keys

val dhcp : ?group:string -> unit -> bool key

Enable dhcp. Is either true or false.

val net : ?group:string -> unit -> [ `Direct | `Socket ] key

The type of stack. Is either "direct" or "socket".

Network keys

val interface : ?group:string -> string -> string key

A network interface.

module V4 : sig ... end

Ipv4 keys.

module V6 : sig ... end

Ipv6 keys.

val syslog : Ipaddr.V4.t option -> Ipaddr.V4.t option key

The address to send syslog frames to.

val syslog_port : int option -> int option key

The port to send syslog frames to.

val syslog_hostname : string -> string key

The hostname to use in syslog frames.

val logs : Mirage_runtime.log_threshold list key
