What is a shadow page table?
The shadow page table is a data structure that is actively maintained and re-filled by the VMM. The shadow page table mirrors what the guest is doing in terms of its own page tables and in terms of what the VMM translates the guest physical address to the host physical address.
How do extended page tables work?
The extended page-table mechanism (EPT) is a feature that can be used to support the virtualization of physical memory. When EPT is in use, certain addresses that would normally be treated as physical addresses (and used to access memory) are instead treated as guest-physical addresses.
What is Intel EPT?
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.
How does a virtual machine monitor work?
Virtual machine monitor (VMM): The program that is used to manage processor scheduling and physical memory allocation. It creates virtual machines by partitioning the actual resources, and interfaces the underlying hardware (virtual operating platform) to all operating systems (both host and guest).
What is the purpose of a shadow page table when a hypervisor is used?
What is the purpose of a shadow page table when a hypervisor is used? It tracks the memory pages allocated by each guest VM. You have been tasked with creating a virtual machine that will require access to the Internet, but should be prevented from sending and receiving packets directly from the physical network.
What is a shadow database?
A shadow database is a database that is built and used inside organizations, without IT knowledge or approval (hence the “shadow” in the title). These databases are usually created by individual employees using Excel spreadsheets, notes on their desktop using Word, or Outlook contact, etc.
Can I run Hyper-V without SLAT?
As you can see, Hyper-V Server 2012 R2 is still fully functional on non-SLAT hardware (whereas Hyper-V Server 2016 isn’t).
Should I enable or disable Intel virtualization technology?
You do not need to disable Virtualization Technology if you are using a VMM or an operating system that does not support AMD-V virtualization. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Virtualization Options > Intel(R) Virtualization Technology (Intel VT).

Does a VM have its own IP address?
A VM has one primary IP address per network adapter. The primary IP address is assigned to the VM by the automatic or manual network it’s attached to. Use the primary IP to access the VM from other machines connected to the same network. See Editing a VM hostname or primary IP address.
What happens when ESXi hosts are put into lockdown mode?
In strict lockdown mode the DCUI service is stopped. If the connection to vCenter Server is lost and the vSphere Web Client is no longer available, the ESXi host becomes unavailable unless the ESXi Shell and SSH services are enabled and Exception Users are defined.
