75 "Libguestfs is a library for accessing and modifying guest disk images. "
76 "Amongst the things this is good for: making batch configuration changes to "
77 "guests, getting disk used/free statistics (see also: virt-df), migrating "
78 "between virtualization systems (see also: virt-p2v), performing partial "
79 "backups, performing partial guest clones, cloning guests and changing "
80 "registry/UUID/hostname info, and much else besides."
84 #: ../src/guestfs.pod:33
86 "Libguestfs uses Linux kernel and qemu code, and can access any type of guest "
87 "filesystem that Linux and qemu can, including but not limited to: ext2/3/4, "

95 "Libguestfs provides ways to enumerate guest storage (eg. partitions, LVs, "

373 #: ../src/guestfs.pod:178
375 "If you are given a disk image and you don't know what it contains then you "

378 "and LVs, and either try mounting each to see what is mountable, or else "

2376 "A raw disk image is just the raw bytes, there is no header. Other disk "
