1334 and sectors on the device, which are passed directly to sfdisk as
1335 the I<-C>, I<-H> and I<-S> parameters. If you pass C<0> for any
1336 of these, then the corresponding parameter is omitted. Usually for
1337 'large' disks, you can just pass C<0> for these, but for small
1338 (floppy-sized) disks, sfdisk (or rather, the kernel) cannot work
1339 out the right geometry and you will need to tell it.
1341 C<lines> is a list of lines that we feed to C<sfdisk>. For more
1342 information refer to the L<sfdisk(8)> manpage.
1344 To create a single partition occupying the whole disk, you would
1345 pass C<lines> as a single element list, when the single element being
1346 the string C<,> (comma).

3304 The inotify subsystem can be used to notify events which happen to

3308 queued up between calls to C<guestfs_inotify_read> or

3311 default is used. For Linux 2.6.29 the default was 16384 events.
3312 Beyond this limit, the kernel throws away events, but records
3313 the fact that it threw them away by setting a flag
3314 C<IN_Q_OVERFLOW> in the returned structure list (see
3315 C<guestfs_inotify_read>).

3320 C<guestfs_inotify_rm_watch> and
3321 C<guestfs_inotify_watch_all>.

3332 watches automatically.

7010 The C<Sys::Guestfs> module provides a Perl XS binding to the
7011 libguestfs API for examining and modifying virtual machine
7014 Amongst the things this is good for: making batch configuration
7015 changes to guests, getting disk used/free statistics (see also:
7016 virt-df), migrating between virtualization systems (see also:
7017 virt-p2v), performing partial backups, performing partial guest
7018 clones, cloning guests and changing registry/UUID/hostname info, and
7021 Libguestfs uses Linux kernel and qemu code, and can access any type of
7022 guest filesystem that Linux and qemu can, including but not limited
7023 to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
7024 schemes, qcow, qcow2, vmdk.
7026 Libguestfs provides ways to enumerate guest storage (eg. partitions,
7027 LVs, what filesystem is in each LV, etc.). It can also run commands
7028 in the context of the guest. Also you can access filesystems over FTP.
7030 See also L<Sys::Guestfs::Lib(3)> for a set of useful library
7031 functions for using libguestfs from Perl, including integration
7036 All errors turn into calls to C<croak> (see L<Carp(3)>).

7528 The guestfs module provides a Python binding to the libguestfs API
7529 for examining and modifying virtual machine disk images.
7531 Amongst the things this is good for: making batch configuration
7532 changes to guests, getting disk used/free statistics (see also:
7533 virt-df), migrating between virtualization systems (see also:
7534 virt-p2v), performing partial backups, performing partial guest
7535 clones, cloning guests and changing registry/UUID/hostname info, and
7538 Libguestfs uses Linux kernel and qemu code, and can access any type of
7539 guest filesystem that Linux and qemu can, including but not limited
7540 to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
7541 schemes, qcow, qcow2, vmdk.
7543 Libguestfs provides ways to enumerate guest storage (eg. partitions,
7544 LVs, what filesystem is in each LV, etc.). It can also run commands
7545 in the context of the guest. Also you can access filesystems over FTP.
7547 Errors which happen while using the API are turned into Python
7548 RuntimeError exceptions.
7550 To create a guestfs handle you usually have to perform the following
7553 # Create the handle, call add_drive at least once, and possibly
7554 # several times if the guest has multiple block devices:
7555 g = guestfs.GuestFS ()
7556 g.add_drive (\"guest.img\")
7558 # Launch the qemu subprocess and wait for it to become ready:
7562 # Now you can issue commands, for example:
7567 import libguestfsmod
