94 "Libguestfs is a library for accessing and modifying guest disk images. "
95 "Amongst the things this is good for: making batch configuration changes to "
96 "guests, getting disk used/free statistics (see also: virt-df), migrating "
97 "between virtualization systems (see also: virt-p2v), performing partial "
98 "backups, performing partial guest clones, cloning guests and changing "
99 "registry/UUID/hostname info, and much else besides."
104 #: ../src/guestfs.pod:33
106 "Libguestfs uses Linux kernel and qemu code, and can access any type of guest "
107 "filesystem that Linux and qemu can, including but not limited to: ext2/3/4, "
108 "btrfs, FAT and NTFS, LVM, many different disk partition schemes, qcow, "

116 "Libguestfs provides ways to enumerate guest storage (eg. partitions, LVs, "
117 "what filesystem is in each LV, etc.). It can also run commands in the "
118 "context of the guest. Also you can access filesystems over FUSE."
123 #: ../src/guestfs.pod:43
125 "Libguestfs is a library that can be linked with C and C++ management "
126 "programs (or management programs written in OCaml, Perl, Python, Ruby, Java, "
127 "PHP, Haskell or C#). You can also use it from shell scripts or the command "
133 #: ../src/guestfs.pod:48

136 "enough permissions to access the disk images."

180 "Before you can use libguestfs calls, you have to create a handle. Then you "
181 "must add at least one disk image to the handle, followed by launching the "
182 "handle, then performing whatever operations you want, and finally closing "

292 "how to handle errors, and consult the documentation for each function call "

310 "through L<posix_fallocate(3)>. Libguestfs lets you do useful things to all "

357 "libguestfs won't modify the file."
362 #: ../src/guestfs.pod:147
364 "Be extremely cautious if the disk image is in use, eg. if it is being used "
365 "by a virtual machine. Adding it read-write will almost certainly cause disk "
366 "corruption, but adding it read-only is safe."
371 #: ../src/guestfs.pod:151
373 "You must add at least one disk image, and you may add multiple disk images. "
374 "In the API, the disk images are usually referred to as C</dev/sda> (for the "
375 "first one you added), C</dev/sdb> (for the second one you added), etc."
380 #: ../src/guestfs.pod:156
382 "Once L</guestfs_launch> has been called you cannot add any more images. You "

397 "image that contains filesystems, you have to mount those filesystems using "
398 "L</guestfs_mount_options> or L</guestfs_mount_ro>. If you already know that "
399 "a disk image contains (for example) one partition with a filesystem on that "
400 "partition, then you can mount it directly:"

415 "disk image that we added (C</dev/sda>). If the disk contains Linux LVM2 "
416 "logical volumes you could refer to those instead (eg. C</dev/VG/LV>). Note "
417 "that these are libguestfs virtual devices, and are nothing to do with host "
422 #: ../src/guestfs.pod:178
424 "If you are given a disk image and you don't know what it contains then you "
425 "have to find out. Libguestfs can do that too: use L</"
426 "guestfs_list_partitions> and L</guestfs_lvs> to list possible partitions and "
427 "LVs, and either try mounting each to see what is mountable, or else examine "
428 "them with L</guestfs_vfs_type> or L</guestfs_file>. To list just "
429 "filesystems, use L</guestfs_list_filesystems>."
433 #: ../src/guestfs.pod:186
435 "Libguestfs also has a set of APIs for inspection of unknown disk images (see "
436 "L</INSPECTION> below). But you might find it easier to look at higher level "

441 #: ../src/guestfs.pod:191
443 "To mount a filesystem read-only, use L</guestfs_mount_ro>. There are "

457 "The majority of the libguestfs API consists of fairly low-level calls for "
458 "accessing and modifying the files, directories, symlinks etc on mounted "
459 "filesystems. There are over a hundred such calls which you can find listed "
460 "in detail below in this man page, and we don't even pretend to cover them "

502 "As another example, to create a top-level directory on that filesystem "
503 "called C<\"var\"> you would do:"

543 "Libguestfs can return errors in many situations: for example if the "
544 "filesystem isn't writable, or if a file or directory that you requested "
545 "doesn't exist. If you are using the C API (documented here) you have to "
546 "check for those error conditions after each call. (Other language bindings "
547 "turn these errors into exceptions)."

2709 #: ../src/guestfs.pod:1234
2711 "A raw disk image is just the raw bytes, there is no header. Other disk "

2721 "This allows a guest which has been given a raw disk image to write some "
2722 "other header. At next boot (or when the disk image is accessed by "

2729 #: ../src/guestfs.pod:1244
2731 "This in itself would not be a problem, but qcow2 offers many features, one "
2732 "of which is to allow a disk image to refer to another image (called the "
2733 "\"backing disk\"). It does this by placing the path to the backing disk "
2734 "into the qcow2 header. This path is not validated and could point to any "
2735 "host file (eg. \"/etc/passwd\"). The backing disk is then exposed through "
2736 "\"holes\" in the qcow2 disk image, which of course is completely under the "
