<command>import-tar</command> is used the file specified as
first argument should be a tar archive, possibly compressed
with xz, gzip or bzip2. It will then be unpacked into its own
subvolume in <filename>/var/lib/machines</filename>. When
<command>import-raw</command> is used the file should be a
qcow2 or raw disk image, possibly compressed with xz, gzip or
bzip2. If the second argument (the resulting image name) is
not specified it is automatically derived from the file
name. If the file name is passed as <literal>-</literal> the
image is read from standard input, in which case the second
argument is mandatory.</para>
