6320 The C<Sys::Guestfs> module provides a Perl XS binding to the
6321 libguestfs API for examining and modifying virtual machine
6324 Amongst the things this is good for: making batch configuration
6325 changes to guests, getting disk used/free statistics (see also:
6326 virt-df), migrating between virtualization systems (see also:
6327 virt-p2v), performing partial backups, performing partial guest
6328 clones, cloning guests and changing registry/UUID/hostname info, and
6331 Libguestfs uses Linux kernel and qemu code, and can access any type of
6332 guest filesystem that Linux and qemu can, including but not limited
6333 to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
6334 schemes, qcow, qcow2, vmdk.
6336 Libguestfs provides ways to enumerate guest storage (eg. partitions,
6337 LVs, what filesystem is in each LV, etc.). It can also run commands
6338 in the context of the guest. Also you can access filesystems over FTP.
6340 See also L<Sys::Guestfs::Lib(3)> for a set of useful library
6341 functions for using libguestfs from Perl, including integration
6346 All errors turn into calls to C<croak> (see L<Carp(3)>).

6818 The guestfs module provides a Python binding to the libguestfs API
6819 for examining and modifying virtual machine disk images.
6821 Amongst the things this is good for: making batch configuration
6822 changes to guests, getting disk used/free statistics (see also:
6823 virt-df), migrating between virtualization systems (see also:
6824 virt-p2v), performing partial backups, performing partial guest
6825 clones, cloning guests and changing registry/UUID/hostname info, and
6828 Libguestfs uses Linux kernel and qemu code, and can access any type of
6829 guest filesystem that Linux and qemu can, including but not limited
6830 to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
6831 schemes, qcow, qcow2, vmdk.
6833 Libguestfs provides ways to enumerate guest storage (eg. partitions,
6834 LVs, what filesystem is in each LV, etc.). It can also run commands
6835 in the context of the guest. Also you can access filesystems over FTP.
6837 Errors which happen while using the API are turned into Python
6838 RuntimeError exceptions.
6840 To create a guestfs handle you usually have to perform the following
6843 # Create the handle, call add_drive at least once, and possibly
6844 # several times if the guest has multiple block devices:
6845 g = guestfs.GuestFS ()
6846 g.add_drive (\"guest.img\")
6848 # Launch the qemu subprocess and wait for it to become ready:
6852 # Now you can issue commands, for example:
