6365 The C<Sys::Guestfs> module provides a Perl XS binding to the
6366 libguestfs API for examining and modifying virtual machine
6369 Amongst the things this is good for: making batch configuration
6370 changes to guests, getting disk used/free statistics (see also:
6371 virt-df), migrating between virtualization systems (see also:
6372 virt-p2v), performing partial backups, performing partial guest
6373 clones, cloning guests and changing registry/UUID/hostname info, and
6376 Libguestfs uses Linux kernel and qemu code, and can access any type of
6377 guest filesystem that Linux and qemu can, including but not limited
6378 to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
6379 schemes, qcow, qcow2, vmdk.
6381 Libguestfs provides ways to enumerate guest storage (eg. partitions,
6382 LVs, what filesystem is in each LV, etc.). It can also run commands
6383 in the context of the guest. Also you can access filesystems over FTP.
6385 See also L<Sys::Guestfs::Lib(3)> for a set of useful library
6386 functions for using libguestfs from Perl, including integration

6863 The guestfs module provides a Python binding to the libguestfs API
6864 for examining and modifying virtual machine disk images.
6866 Amongst the things this is good for: making batch configuration
6867 changes to guests, getting disk used/free statistics (see also:
6868 virt-df), migrating between virtualization systems (see also:
6869 virt-p2v), performing partial backups, performing partial guest
6870 clones, cloning guests and changing registry/UUID/hostname info, and
6873 Libguestfs uses Linux kernel and qemu code, and can access any type of
6874 guest filesystem that Linux and qemu can, including but not limited
6875 to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
6876 schemes, qcow, qcow2, vmdk.
6878 Libguestfs provides ways to enumerate guest storage (eg. partitions,
6879 LVs, what filesystem is in each LV, etc.). It can also run commands
6880 in the context of the guest. Also you can access filesystems over FTP.
6882 Errors which happen while using the API are turned into Python
6883 RuntimeError exceptions.
6885 To create a guestfs handle you usually have to perform the following
6888 # Create the handle, call add_drive at least once, and possibly
6889 # several times if the guest has multiple block devices:
6890 g = guestfs.GuestFS ()
6891 g.add_drive (\"guest.img\")
6893 # Launch the qemu subprocess and wait for it to become ready:
6897 # Now you can issue commands, for example:
