I am working on them. Is there any way to enable vt-x[EPT] for Dom0. I am trying to do something like what bitvisor has done, but using vastly helpful functionalities of xen. And I need to ask; would we see any performance improvement if we do this? I know that virtual memory mechanism like shadow paging will isolate dom0, and xen from each other. Implementation of virtual BIOS also will help to prevent to use something like INT 15 to pass it through. In the other words, Do we have isolation of xen, and Dom0 without even using VT-x? -- Best Regards, Mohamad Rezaei
