>From the previous post I learned that Xen haven't implement CPU's VT
feature for HVM's vcpu.
So I guess it is the same about hardware DEP (Data Execution
Protection) feature that is related to Intel's DX or AMD's NX bit.
(correct me if I'm wrong.)
Currently I have a Windows application using hardware DEP and I want
to port it to Xen's HVM.
Is there any alternative way to support hardware DEP in HVM? or any
suggestions on how to modify Xen to achieve it? Thanks.
