The $DATASTORE_LOCATION/<id> dir is created by the first VM deployment.
That is why in HostXML::test_ds_capacity (called from Scheduler.cc), we use
HOST/FREE_DISK as the free space when the ds-id subdir does not exist, to
allow the first deployment.

But now it seems that monitor_ds should also consider that
$DATASTORE_LOCATION may actually not exist.
