https://bugzilla.redhat.com/show_bug.cgi?id=1455819 It may happen that a domain is started without any huge pages. However, user might try to attach a DIMM module later. DIMM backed by huge pages (why would somebody want to mix regular and huge pages is beyond me). Therefore we have to create the dir if we haven't done so far.
