If you specify guest block devices directly (I<-a>), then libvirt is
not used at all.
+=item B<--csv>
+
+Write out the results in CSV format (comma-separated values). This
+format can be imported easily into databases and spreadsheets, but
+read L</NOTE ABOUT CSV FORMAT> below.

-Add all the disks from the named libvirt guest.
+Add all the disks from the named libvirt guest. Domain UUIDs can be

You are not allowed to use I<-h> and I<--csv> at the same time.

+=item B<-i>

+=item B<--inodes>
Print inodes instead of blocks.

+=head1 STATVFS NUMBERS
+
+C<virt-df> (and L<df(1)>) get information by issuing a L<statvfs(3)>
+system call. You can get the same information directly, either from
+the host (using libguestfs) or inside the guest:
+
+=over 4
+
+=item From the host
+
+Run this command:
+
+ guestfish --ro -d GuestName -i statvfs /

+(change C</> to see stats for other filesystems).
+
+=item From inside the guest
+
+Run this command:
+
+ python -c 'import os; s = os.statvfs ("/"); print s'
+
+(change C</> to see stats for other filesystems).

=head1 NOTE ABOUT CSV FORMAT
Comma-separated values (CSV) is a deceptive format. It I<seems> like
quote or escape these characters on the command line. See the shell
manual page L<sh(1)> for details.
+=head1 EXIT STATUS
+
+This program returns 0 if successful, or non-zero if there was an
