32 virt-list-filesystems - List filesystems in a virtual machine or disk image
36 virt-list-filesystems [--options] domname

42 C<virt-list-filesystems> is a command line tool to list
43 the filesystems that are contained in a virtual machine or
46 C<virt-list-filesystems> is just a simple wrapper around
47 L<libguestfs(3)> functionality. For more complex cases you should
48 look at the L<guestfish(1)> tool.
68 Display version number and exit.
74 =item B<--connect URI> | B<-c URI>
76 If using libvirt, connect to the given I<URI>. If omitted, then we
77 connect to the default libvirt hypervisor.
79 If you specify guest block devices directly, then libvirt is not used
88 Specify the format of disk images given on the command line. If this
89 is omitted then the format is autodetected from the content of the
92 If disk images are requested from libvirt, then this program asks
93 libvirt for this information. In this case, the value of the format

97 ensure the format is always specified.

105 With this option, C<virt-list-filesystems> displays the type of
106 each filesystem too (where "type" means C<ext3>, C<xfs> etc.)

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

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