What is an extended page table?
Extended Page Tables (EPT) is an Intel second-generation x86 virtualization technology for the memory management unit (MMU). EPT support is found in Intel’s Core i3, Core i5, Core i7 and Core i9 CPUs, among others. It is also found in some newer VIA CPUs.
What are nested page tables?
Under nested paging, the processor utilizes nested page tables, which are set up by the hypervisor, to perform a second level address translation. Nested Paging reduces the overheads found in equivalent shadow paging implementations.
What does enabling Intel virtualization do?
Intel Virtualization Technology (Intel VT or IVT) is a capability provided in Intel processors that enables multiple operating systems and environments to consolidate and host on a single processor.

What is Intel VTX and Vtd?
VT-x is the actual hardware virtualisation assistance – absolute necessary, whereas VT-d allows you direct passthrough of devices, such as PCI devices, not essential in PC environments but nice to have when running server (vSphere server where you need RAID cards passed through directly to the guest etc.).
How do I disable nested paging?
If you’re not familiar with this setting. Shut down your virtual machine so that you can edit the settings. Then go to the system tab, click on Acceleration and then uncheck the Enable Nested Paging checkbox.

Should I disable Intel VT-d?
VTd allows direct access to the hardware from the virtual machine. You do not need it to be enabled, but I don’t see any reason why you would want to not enable it. Turn it on. My Computers.
How do I enable nested paging?
If nested paging is enabled, the VirtualBox hypervisor can also use large pages to reduce TLB usage and overhead. This can yield a performance improvement of up to 5%. To enable this feature for a VM, you need to use the VBoxManage modifyvm –largepages command; see “VBoxManage modifyvm”.
What are shadow page tables?
A shadow page table is a pseudo-page table within a computer’s main page table which allows a system to run more than one kind of operating system concurrently.
