>From the previous post I learned that Xen haven''t implement CPU''s VTfeature 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?

Re: [Xen-devel] How to support hardware DEP feature in HVM?
Support for NX bit is exposed to HVM guests, so your application should work. -- Keir On 26/03/2009 08:07, "Yanjun Wu" <yanjun.wu@gmail.com> wrote:>> 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?
