This is equivalent to the qemu parameter C<-cdrom filename>.
+Note that this call checks for the existence of C<filename>. This

+This adds a drive in snapshot mode, making it effectively
+read-only.
+
+Note that writes to the device are allowed, and will be seen for
+the duration of the guestfs handle, but they are written
+to a temporary file which is discarded as soon as the guestfs
+handle is closed. We don't currently have any method to enable
+changes to be committed, although qemu can support this.

This moves a file from C<src> to C<dest> where C<dest> is
either a destination filename or destination directory.
+=head2 ntfs-3g-probe
+
+ ntfs-3g-probe true|false device
+
+This command runs the L<ntfs-3g.probe(8)> command which probes
+an NTFS C<device> for mountability. (Not all NTFS volumes can
+be mounted read-write, and some cannot be mounted at all).
+
+C<rw> is a boolean flag. Set it to true if you want to test
+if the volume can be mounted read-write. Set it to false if
+you want to test if the volume can be mounted read-only.
+
+The return value is an integer which C<0> if the operation
+would succeed, or some non-zero value documented in the
+L<ntfs-3g.probe(8)> manual page.
