3527 If this is passed as C<0>, then the kernel (or previously set)
3528 default is used. For Linux 2.6.29 the default was 16384 events.
3529 Beyond this limit, the kernel throws away events, but records
3530 the fact that it threw them away by setting a flag
3531 C<IN_Q_OVERFLOW> in the returned structure list (see
3532 C<guestfs_inotify_read>).
3534 Before any events are generated, you have to add some
3535 watches to the internal watch list. See:
3536 C<guestfs_inotify_add_watch>,
3537 C<guestfs_inotify_rm_watch> and
3538 C<guestfs_inotify_watch_all>.
3540 Queued up events should be read periodically by calling
3541 C<guestfs_inotify_read>
3542 (or C<guestfs_inotify_files> which is just a helpful
3543 wrapper around C<guestfs_inotify_read>). If you don't
3544 read the events out often enough then you risk the internal

3549 watches automatically.

4205 The libguestfs groups, and the functions that those
4206 groups correspond to, are listed in L<guestfs(3)/AVAILABILITY>.

4219 list of groups then an error is always returned.

8651 The C<Sys::Guestfs> module provides a Perl XS binding to the
8652 libguestfs API for examining and modifying virtual machine
8655 Amongst the things this is good for: making batch configuration
8656 changes to guests, getting disk used/free statistics (see also:
8657 virt-df), migrating between virtualization systems (see also:
8658 virt-p2v), performing partial backups, performing partial guest
8659 clones, cloning guests and changing registry/UUID/hostname info, and
8662 Libguestfs uses Linux kernel and qemu code, and can access any type of
8663 guest filesystem that Linux and qemu can, including but not limited
8664 to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
8665 schemes, qcow, qcow2, vmdk.
8667 Libguestfs provides ways to enumerate guest storage (eg. partitions,
8668 LVs, what filesystem is in each LV, etc.). It can also run commands
8669 in the context of the guest. Also you can access filesystems over
8672 See also L<Sys::Guestfs::Lib(3)> for a set of useful library
8673 functions for using libguestfs from Perl, including integration

9190 The guestfs module provides a Python binding to the libguestfs API
9191 for examining and modifying virtual machine disk images.
9193 Amongst the things this is good for: making batch configuration
9194 changes to guests, getting disk used/free statistics (see also:
9195 virt-df), migrating between virtualization systems (see also:
9196 virt-p2v), performing partial backups, performing partial guest
9197 clones, cloning guests and changing registry/UUID/hostname info, and
9200 Libguestfs uses Linux kernel and qemu code, and can access any type of
9201 guest filesystem that Linux and qemu can, including but not limited
9202 to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
9203 schemes, qcow, qcow2, vmdk.
9205 Libguestfs provides ways to enumerate guest storage (eg. partitions,
9206 LVs, what filesystem is in each LV, etc.). It can also run commands
9207 in the context of the guest. Also you can access filesystems over
9210 Errors which happen while using the API are turned into Python
9211 RuntimeError exceptions.
9213 To create a guestfs handle you usually have to perform the following
9216 # Create the handle, call add_drive at least once, and possibly
9217 # several times if the guest has multiple block devices:
9218 g = guestfs.GuestFS ()
9219 g.add_drive (\"guest.img\")
9221 # Launch the qemu subprocess and wait for it to become ready:
9224 # Now you can issue commands, for example:
