+=item B<domfstrim> I<domain> [I<--minimum> B<bytes>]
+[I<--mountpoint mountPoint>]
+
+Issue a fstrim command on all mounted filesystems within a running
+domain. It discards blocks which are not in use by the filesystem.
+If I<--minimum> B<bytes> is specified, it tells guest kernel length
+of contiguous free range. Smaller than this may be ignored (this is
+a hint and the guest may not respect it). By increasing this value,
+the fstrim operation will complete more quickly for filesystems
+with badly fragmented free space, although not all blocks will
+be discarded. The default value is zero, meaning "discard
+every free block". Moreover, a if user wants to trim only one mount
+point, it can be specified via optional I<--mountpoint> parameter.
+
=item B<domhostname> I<domain>
Returns the hostname of a domain, if the hypervisor makes it available.
