37 virt-list-filesystems [--options] domname

43 C<virt-list-filesystems> is a command line tool to list
44 the filesystems that are contained in a virtual machine or
47 C<virt-list-filesystems> is just a simple wrapper around
48 L<libguestfs(3)> functionality. For more complex cases you should
49 look at the L<guestfish(1)> tool.
69 Display version number and exit.
75 =item B<--connect URI> | B<-c URI>
77 If using libvirt, connect to the given I<URI>. If omitted, then we
78 connect to the default libvirt hypervisor.
80 If you specify guest block devices directly, then libvirt is not used
87 =item B<-l> | B<--long>
89 With this option, C<virt-list-filesystems> displays the type of
90 each filesystem too (where "type" means C<ext3>, C<xfs> etc.)
96 =item B<-a> | B<--all>
98 Normally we only show mountable filesystems. If this option
99 is given then swap devices are shown too.
