The guest operating system USES APIs, provided by virtual machine monitor (VMM), to communicate with the hypervisor to directly access certain resources on the underlying hardware.

Figure 1 shows that the virtualization component is provided by a layer of software called a hypervisor (sometimes called a virtual machine monitor [VMM]).

图1中所示的这个虚拟化组件是由一个名为hypervisor(有时也叫作虚拟机监视器[VMM])的软件层提供的。

In a typical layered architecture, the layer that provides for the platform virtualization is called the hypervisor (sometimes called the virtual machine monitor, or VMM).

在典型的分层架构中，提供平台虚拟化的层称为hypervisor(有时称为虚拟机管理程序或VMM)。

The flaw, which affected the virtual machine monitor (VMM) in Virtual PC, could enable an attacker to use applications running in user-space on a guest OS to access portions of the Virtual PC memory that should be inaccessible to those applications.
