The CPU needs to access the memory through the physical address of the host. If it is just a physical server, this physical address is only for one operating system, but if virtualized deployment is performed and there are multiple virtual machines, there is a hidden danger of stability. Because when VM Entry (virtual machine entry) and VM EXIT (especially the latter), the memory pages must be modified. However, physical memory is shared by multiple virtual machines, so the virtual machine cannot directly access the physical address, otherwise a virtual machine will have memory errors, which will affect the operation of the entire physical server. Therefore, the virtual address must be adopted, and the role of EPT is to accelerate the conversion process from the virtual machine address to the physical address of the host, and save system overhead to save traditional software processing methods.
