5713 The C<Sys::Guestfs> module provides a Perl XS binding to the
5714 libguestfs API for examining and modifying virtual machine
5717 Amongst the things this is good for: making batch configuration
5718 changes to guests, getting disk used/free statistics (see also:
5719 virt-df), migrating between virtualization systems (see also:
5720 virt-p2v), performing partial backups, performing partial guest
5721 clones, cloning guests and changing registry/UUID/hostname info, and
5724 Libguestfs uses Linux kernel and qemu code, and can access any type of
5725 guest filesystem that Linux and qemu can, including but not limited
5726 to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
5727 schemes, qcow, qcow2, vmdk.
5729 Libguestfs provides ways to enumerate guest storage (eg. partitions,
5730 LVs, what filesystem is in each LV, etc.). It can also run commands
5731 in the context of the guest. Also you can access filesystems over FTP.
5735 All errors turn into calls to C<croak> (see L<Carp(3)>).

6231 The guestfs module provides a Python binding to the libguestfs API
6232 for examining and modifying virtual machine disk images.
6234 Amongst the things this is good for: making batch configuration
6235 changes to guests, getting disk used/free statistics (see also:
6236 virt-df), migrating between virtualization systems (see also:
6237 virt-p2v), performing partial backups, performing partial guest
6238 clones, cloning guests and changing registry/UUID/hostname info, and
6241 Libguestfs uses Linux kernel and qemu code, and can access any type of
6242 guest filesystem that Linux and qemu can, including but not limited
6243 to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
6244 schemes, qcow, qcow2, vmdk.
6246 Libguestfs provides ways to enumerate guest storage (eg. partitions,
6247 LVs, what filesystem is in each LV, etc.). It can also run commands
6248 in the context of the guest. Also you can access filesystems over FTP.
6250 Errors which happen while using the API are turned into Python
6251 RuntimeError exceptions.
6253 To create a guestfs handle you usually have to perform the following
6256 # Create the handle, call add_drive at least once, and possibly
6257 # several times if the guest has multiple block devices:
6258 g = guestfs.GuestFS ()
6259 g.add_drive (\"guest.img\")
6261 # Launch the qemu subprocess and wait for it to become ready:
6265 # Now you can issue commands, for example:
6270 import libguestfsmod
