Interesting, Clayton...that is the way I've been going with this today. :)
Is that to say that CS cannot currently create a Primary Storage type in a
Cluster under Xen unless you pre-configure the storage and select PreSetup?
 Just curious to learn about some of the restrictions in CS.  Also, if that
is the case, how does a user learn about such a restriction?

Thanks!
