例如，来宾操作系统不能禁用中断，以使这些请求在宿主操作系统中执行。
For example, the guest cannot disable interrupts, so these requests are performed in the host operating system.
虚拟化player在宿主操作系统上运行，向访客操作系统提供完整的硬件虚拟化。
Virtualization players run on host operating systems and provide the complete hardware virtualization to the guest operating systems.
VMware随后推出了ESXServer，它可以运行在裸机上并且不需要宿主操作系统。
This was followed by VMware's ESX Server, which runs on bare metal and does not require a host operating system.
使用Lguest这种方法还减少了总代码需求，仅需在来宾操作系统和宿主操作系统中使用一个瘦层。
The Lguest approach also simplifies the overall code requirements, requiring only a thin layer in the guest and also in the host operating system.
当新的操作系统在KVM上启动时（通过一个称为 kvm的实用程序），它就成为宿主操作系统的一个进程，因此就可以像其他进程一样调度它。
When a new operating system is booted on KVM (through a utility called kvm), it becomes a process of the host operating system and therefore scheduleable like any other process.
然而我们希望(Chrome在其他系统上的外观)能够符合宿主操作系统的外观，这意味着需要使用本地的文本渲染调用以便我们能使用诸如windows的ClearType等技术。
However, we wanted to match the host OS's look and feel. This means using native text rendering routines so that, for example, we can get ClearType on Windows.
首先，类似于将用户空间应用程序和内核函数连接起来的系统调用，一个通常可用的虚拟化调用(hapercall, hypervisor对操作系统进行的系统调用)层允许来宾系统向宿主操作系统发出请求。
First, similar to system calls that bridge user-space applications with kernel functions, a hypercall layer is commonly available that allows guests to make requests of the host operating system.
这个模块包含来宾操作系统通向宿主内核的接口。
This module contains the guest operating system's interface to the host kernel.
对于一般的从业人员来讲，他们的第一反应会是在一个宿主机上运行一个或多个虚拟(客户)操作系统。
The first concept that comes to the mind of the average industry professional is running one or more guest operating systems on a host.
访客必须使用与宿主相同的操作系统(见图4)。
Guests must use the same operating system as the host shown below in Figure 4.
这个模块允许使用其他客户操作系统，然后在宿主Linux内核的用户空间中运行(参见图7)。
This module allows other guest operating systems to then run in user-space of the host Linux kernel (see Figure 7).
这里需要注意的是，libvirt（及其应用程序）在宿主Linux操作系统（域0）中运行。
Note here that libvirt (and its application) runs in the domain of the host Linux operating system (domain 0).
在这种模型中，宿主运行单一OS内核并向每个访客操作系统导出操作系统功能。
In this model, the host runs a single OS kernel as its core and exports operating system functionality to each of the guest operating systems.
每个客户Linux操作系统都存在于宿主Linux操作系统中的一个进程中(参见图6)。
Each guest Linux operating system exists within a process of the host Linux operating system (see Figure 6).
通知宿主托管代码正在进入不能在其间将当前任务移动到另一个操作系统线程的周期。
Notifies the host that managed code is exiting the period in which the current task must not be moved to another operating system thread, following an earlier call to BeginThreadAffinity.
通知宿主托管代码正在进入不能在其间将当前任务移动到另一个操作系统线程的周期。
Notifies the host that managed code is exiting the period in which the current task must not be moved to another operating system thread, following an earlier call to BeginThreadAffinity.
