|
|
val uri_quote : string -> string
|
|
(** Take a string and perform %xx escaping as used in some parts of URLs. *)
|
|
|
|
val kvm_arch : string -> string
|
|
(** Map guest architecture found by inspection to the architecture
|
|
that KVM must emulate. Note for x86 we assume a 64 bit hypervisor. *)

val qemu_supports_sound_card : Types.source_sound_model -> bool
|
|
(** Does qemu support the given sound card? *)
|
|
|

val find_uefi_firmware : string -> Uefi.uefi_firmware
|
|
(** Find the UEFI firmware for the guest architecture.
|
|
This cannot return an error, it calls [error] and fails instead. *)

|
|
(** Compare two app versions. *)

|
val du : string -> int64
|
|
(** Return the true size of a file in bytes, including any wasted
|
|
space caused by internal fragmentation (the overhead of using
|
|
blocks).
|
|
|
|
This can raise either [Failure] or [Invalid_argument] in case
|
|
of errors. *)

val qemu_img_supports_offset_and_size : unit -> bool
|
|
(** Return true iff [qemu-img] supports the ["offset"] and ["size"]
|
|
parameters to open a subset of a file. *)

(** Return true iff the current backend is libvirt. *)

|
|
(** [find_file_in_tar tar filename] looks up file in [tar] archive and returns
|
|
a tuple containing at which byte it starts and how long the file is.
|
|
|
|
Function raises [Not_found] if there is no such file inside [tar] and
|
|
[Failure] if there is any error parsing the tar output. *)
