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 FTP.
+See also L<Sys::Guestfs::Lib(3)> for a set of useful library
+functions for using libguestfs from Perl, including integration
+with libvirt.

=head1 ERRORS
All errors turn into calls to C<croak> (see L<Carp(3)>).
