in software developement is there a tradeoff between the two and how can it be viable economically and technologically.
Hi, i'm creating a hypervisor based on Intel-vt extensions, each VM must be able to have it's own hypervisor with Intel-vt (i don't have choice).
The probleme is to use a hypervisor into a VM with Intel-VT require to be in root-operation to perfectly use virtualization instructions such as VMCALL, VMREAD ... But each vm-exit will only give control to the first hypervisor.
So the sub-monitor will never be used.
How can i do that ? Is nested virtualization with Intel-VT is realy possible without modifying guest ?
Thanks a lot.
I'm trying to find out what does the Microsoft Hypervisor register for as its control fields.
What registers do I need to be looking at it to find this? The documentaiton is unclear as to where the registers are that control the fields. It keeps saying bitmaps .. but to what.
I would like to the overhead of VMEntry and VMExit. Is there any publication talking about this?
Anbody have this issue? HP EliteBook 8760w, BIOS F.25, 16GB (4x4GB) ram, Intel Core i7-2820QM with Intel VT-x enabled, Win7 Enterprise 64-bit, VMware Workstation 8.0.4.

Hi,There is some confusion over if the i7 3930K C2 stepping can support EPT as part of its VT-x abilities. Some of the martieral on the Intel site say no while others have said that it does depending on the motherboard used.Could someone please clarify?Thanks,David.
is there an option to find out at runtime (e.g. with means of CPUID or something else) if the "Unrestricted Guest" feature is supported on the CPU? In the developer manual I can only find which flags control the UG feature (i.e. "25.8. Unrestricted Guests" ff), but I don't see anywhere how to determine if the feature is actually supported. Historically, at which processor family was "Unrestricted Guest" introduced? Is there a easy way to tell which processors contian the feature from the timeline?
