"""Python bindings for libguestfs

import guestfs
g = guestfs.GuestFS (python_return_dict=True)
g.add_drive_opts ("guest.img", format="raw")
g.launch ()
parts = g.list_partitions ()

The guestfs module provides a Python binding to the libguestfs API
for examining and modifying virtual machine disk images.

Amongst the things this is good for: making batch configuration
changes to guests, getting disk used/free statistics (see also:
virt-df), migrating between virtualization systems (see also:
virt-p2v), performing partial backups, performing partial guest
clones, cloning guests and changing registry/UUID/hostname info, and
much else besides.

Libguestfs uses Linux kernel and qemu code, and can access any type of
guest filesystem that Linux and qemu can, including but not limited
to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
schemes, qcow, qcow2, vmdk.

Libguestfs provides ways to enumerate guest storage (eg. partitions,
LVs, what filesystem is in each LV, etc.).  It can also run commands
in the context of the guest.  Also you can access filesystems over
FUSE.

Errors which happen while using the API are turned into Python
RuntimeError exceptions.

To create a guestfs handle you usually have to perform the following
sequence of calls:

# Create the handle, call add_drive* at least once, and possibly
# several times if the guest has multiple block devices:
g = guestfs.GuestFS ()
g.add_drive_opts ("guest.img", format="raw")

# Launch the qemu subprocess and wait for it to become ready:
g.launch ()

# Now you can issue commands, for example:
logvols = g.lvs ()

        When this function is called before "g.launch" (the
        usual case) then the first time you call this function,
        the disk appears in the API as "/dev/sda", the second
        time as "/dev/sdb", and so on.
        
        In libguestfs ≥ 1.20 you can also call this function
        after launch (with some restrictions). This is called
        "hotplugging". When hotplugging, you must specify a
        "label" so that the new disk gets a predictable name.
        For more information see "HOTPLUGGING" in guestfs(3).
        
        You don't necessarily need to be root when using
        libguestfs. However you obviously do need sufficient
        permissions to access the filename for whatever
        operations you want to perform (ie. read access if you
        just want to read the image or write access if you want
        to modify the image).
        
        This call checks that "filename" exists.
        
        "filename" may be the special string "/dev/null". See
        "NULL DISKS" in guestfs(3).
        
        The optional arguments are:
        
        "readonly"
        If true then the image is treated as read-only.
        Writes are still allowed, but they are stored in a
        temporary snapshot overlay which is discarded at the
        end. The disk that you add is not modified.
        
        "format"
        This forces the image format. If you omit this (or
        use "g.add_drive" or "g.add_drive_ro") then the
        format is automatically detected. Possible formats
        include "raw" and "qcow2".
        
        Automatic detection of the format opens you up to a
        potential security hole when dealing with untrusted
        raw-format images. See CVE-2010-3851 and
        RHBZ#642934. Specifying the format closes this
        security hole.
        
        "iface"
        This rarely-used option lets you emulate the
        behaviour of the deprecated "g.add_drive_with_if"
        call (q.v.)
        
        "name"
        The name the drive had in the original guest, e.g.
        "/dev/sdb". This is used as a hint to the guest
        inspection process if it is available.
        
        "label"
        Give the disk a label. The label should be a unique,
        short string using *only* ASCII characters
        "[a-zA-Z]". As well as its usual name in the API
        (such as "/dev/sda"), the drive will also be named
        "/dev/disk/guestfs/*label*".
        
        See "DISK LABELS" in guestfs(3).

        sheepdog       Zero or more
        ssh            Exactly one
        
        Each list element is a string specifying a server.
        The string must be in one of the following formats:
        
        hostname
        hostname:port
        tcp:hostname
        tcp:hostname:port
        unix:/path/to/socket
        
        If the port number is omitted, then the standard
        port number for the protocol is used (see
        "/etc/services").
        
        "username"
        For the "ftp", "ftps", "http", "https", "iscsi",
        "rbd", "ssh" and "tftp" protocols, this specifies
        the remote username.
        
        If not given, then the local username is used for
        "ssh", and no authentication is attempted for ceph.
        But note this sometimes may give unexpected results,
        for example if using the libvirt backend and if the
        libvirt backend is configured to start the qemu
        appliance as a special user such as "qemu.qemu". If
        in doubt, specify the remote username you want.
        
        "secret"
        For the "rbd" protocol only, this specifies the
        'secret' to use when connecting to the remote
        device.
        
        If not given, then a secret matching the given
        username will be looked up in the default keychain
        locations, or if no username is given, then no
        authentication will be used.

        guest, and should be treated with caution. PNG files
        have been known to contain exploits. Ensure that
        libpng (or other relevant libraries) are fully up to
        date before trying to process or display the icon.
        
        *   The PNG image returned can be any size. It might not
        be square. Libguestfs tries to return the largest,
        highest quality icon available. The application must
        scale the icon to the required size.
        
        *   Extracting icons from Windows guests requires the
        external "wrestool" program from the "icoutils"
        package, and several programs ("bmptopnm",
        "pnmtopng", "pamcut") from the "netpbm" package.
        These must be installed separately.

        These calls are *only* necessary in some very limited
        circumstances, mainly the case where you want to mount a
        mix of unrelated and/or read-only filesystems together.
        
        For example, live CDs often contain a "Russian doll"
        nest of filesystems, an ISO outer layer, with a squashfs
        image inside, with an ext2/3 image inside that. You can
        unpack this as follows in guestfish:
        
        add-ro Fedora-11-i686-Live.iso
        run
        mkmountpoint /cd
        mkmountpoint /sqsh
        mkmountpoint /ext3fs
        mount /dev/sda /cd
        mount-loop /cd/LiveOS/squashfs.img /sqsh
        mount-loop /sqsh/LiveOS/ext3fs.img /ext3fs
        
        The inner filesystem is now unpacked under the /ext3fs
        mountpoint.
        
        "g.mkmountpoint" is not compatible with "g.umount_all".
        You may get unexpected errors if you try to mix these
        calls. It is safest to manually unmount filesystems and
        remove mountpoints after use.
        
        "g.umount_all" unmounts filesystems by sorting the paths
        longest first, so for this to work for manual
        mountpoints, you must ensure that the innermost
        mountpoints have the longest pathnames, as in the
        example code above.
        
        For more details see
        <https://bugzilla.redhat.com/show_bug.cgi?id=599503>
        
        Autosync [see "g.set_autosync", this is set by default
        on handles] can cause "g.umount_all" to be called when
        the handle is closed which can also trigger these
        issues.
