In hindsight, that makes sense (though I swear I disabled root-squashing). I've 
been having other issues now, so quick question;

Most guides referer/specify XenServer 6.0.2, should 6.0 work (due to 6.0.2 
being temporarily unavailable?). 

I'm going to try now with XenServer 6.0 and build remotely. 

Another quick question:

Should this all work on a completely vanilla install of XenServer or XCP or is 
there any prep-work not mentioned anywhere, or any steps a complete Xen newb 
may miss?
