The current architecture of Xen requires that we trust whatever is 
running in Domain-0.  The problems being cited wouldn't be a problem if 
you could create domains from unpriviledged Domains because you could 
have creator Domains who could be created from a trusted source and used 
as a buffer against attack.

No matter what, you're trusting some non-Xen piece of software to 
enforce security within Domain-0, unless the next step in Xen is to 
write a Domain-0 OS :-)
