79 If using libvirt, connect to the given I<URI>. If omitted, then we
80 connect to the default libvirt hypervisor.
82 If you specify guest block devices directly, then libvirt is not used
91 Specify the format of disk images given on the command line. If this

100 ensure the format is always specified.

109 each filesystem too (where "type" means C<ext3>, C<xfs> etc.)

117 Normally we only show mountable filesystems. If this option
118 is given then swap devices are shown too.

184 Libvirt guest names can contain arbitrary characters, some of which
185 have meaning to the shell such as C<#> and space. You may need to
186 quote or escape these characters on the command line. See the shell
187 manual page L<sh(1)> for details.
