You can drop to the shell using F2 and create the directory that way.  

IMO, since we restrict the location you can create a local data store,
we should automatically create that when configuring the local
datastore.  

We can't actually pre-create the directory since it's a mounted
filesystem, but it might be possible to do it at installation or boot
time.  The right place is in vdsm when it's trying to create the local
data store.

Dan,  is this possible to do?  Isn't /data2/images also a possible
location?

Thanks
