Re: [Xen-devel] how does nested xen translate memory address?

[quizyjones <quizy_jones@xxxxxxxxxxx>]

In addition, how can I obtain the physical address range of the nested Xen? By 
default, I can obtain its virtual address from xen-syms file, but I don't think 
it is equal to its physical address, as there are two Xens (L0 and L1) 
co-exists.
