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).

3306 The inotify subsystem can be used to notify events which happen to

3313 default is used. For Linux 2.6.29 the default was 16384 events.
3314 Beyond this limit, the kernel throws away events, but records
3315 the fact that it threw them away by setting a flag
3316 C<IN_Q_OVERFLOW> in the returned structure list (see
3317 C<guestfs_inotify_read>).

3322 C<guestfs_inotify_rm_watch> and
3323 C<guestfs_inotify_watch_all>.

7012 The C<Sys::Guestfs> module provides a Perl XS binding to the
7013 libguestfs API for examining and modifying virtual machine
7016 Amongst the things this is good for: making batch configuration
7017 changes to guests, getting disk used/free statistics (see also:
7018 virt-df), migrating between virtualization systems (see also:
7019 virt-p2v), performing partial backups, performing partial guest
7020 clones, cloning guests and changing registry/UUID/hostname info, and
7023 Libguestfs uses Linux kernel and qemu code, and can access any type of
7024 guest filesystem that Linux and qemu can, including but not limited
7025 to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
7026 schemes, qcow, qcow2, vmdk.
7028 Libguestfs provides ways to enumerate guest storage (eg. partitions,
7029 LVs, what filesystem is in each LV, etc.). It can also run commands
7030 in the context of the guest. Also you can access filesystems over FTP.
7032 See also L<Sys::Guestfs::Lib(3)> for a set of useful library
7033 functions for using libguestfs from Perl, including integration
7038 All errors turn into calls to C<croak> (see L<Carp(3)>).

7530 The guestfs module provides a Python binding to the libguestfs API
7531 for examining and modifying virtual machine disk images.
7533 Amongst the things this is good for: making batch configuration
7534 changes to guests, getting disk used/free statistics (see also:
7535 virt-df), migrating between virtualization systems (see also:
7536 virt-p2v), performing partial backups, performing partial guest
7537 clones, cloning guests and changing registry/UUID/hostname info, and
7540 Libguestfs uses Linux kernel and qemu code, and can access any type of
7541 guest filesystem that Linux and qemu can, including but not limited
7542 to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
7543 schemes, qcow, qcow2, vmdk.
7545 Libguestfs provides ways to enumerate guest storage (eg. partitions,
7546 LVs, what filesystem is in each LV, etc.). It can also run commands
7547 in the context of the guest. Also you can access filesystems over FTP.
7549 Errors which happen while using the API are turned into Python
7550 RuntimeError exceptions.
7552 To create a guestfs handle you usually have to perform the following
7555 # Create the handle, call add_drive at least once, and possibly
7556 # several times if the guest has multiple block devices:
7557 g = guestfs.GuestFS ()
7558 g.add_drive (\"guest.img\")
7560 # Launch the qemu subprocess and wait for it to become ready:
7564 # Now you can issue commands, for example:
