virtual IP addressA virtual IP address (VIP or VIPA) is an IP address assigned to multiple applications residing on a single server, multiple domain names, or multiple servers, rather than being assigned to a specific single server or network interface card (NIC). Incoming data packets are sent to the VIP address which are routed to actual network interface

this virtual interface would consist of the expected interface, including a virtual address space representing the device (such as shadow pci) and virtual interrupt.
这个虚拟接口包含预期的接口,包括表示设备(如shadowpci)的虚拟地址空间和虚拟中断。
thus a portion of the virtual address space must be reserved to the kernel
也就是说,操作系统内核将保留一部分虚拟地址空间。
a dsi occurs whenever a reference is made to a virtual address that is not currently loaded in physical memory (this is a page fault).
如果对当前不在物理内存中加载的虚拟地址进行引用(这是一个页面错误),则会出现dsi错误。
tlb is the cache holding the mapping information from the virtual address to the physical page in memory.
tlb缓存包含从虚拟地址到内存中物理页面的映射信息。
for every page mapped by each process, page-table entries must also be created to map the virtual address to the physical address.
由于每个页都要由每个进程映射,必须创建页表条目来将虚拟地址映射到物理地址。
this 4gb range represents the process「 maximum theoretical extent and (together sometimes with the vmm」s structures that represent it), is known as the virtual address space of the process.
其中4gb范围表示进程的最大理论范围(有时包括用于表示它的vmm结构),被称为进程的虚拟地址空间。
this sandbox is the virtual address space , which in 32-bit mode is always a 4gb block of memory addresses .
所谓「沙盒」,是指虚拟地址空间 ,在32位模式下,虚拟地址空间 最多能表示4gb容量 。
when a program tries to access memory using a virtual address, the os in combination with on-chip hardware maps that virtual address to the physical location.
当程序尝试使用虚拟地址访问内存时,操作系统结合片上硬件将该虚拟地址映射到物理位置。
overwriting a local variable that is near the buffer in memory of a given process「s virtual address space to change the behavior of the application.
重写靠近缓沖区(保存给定进??的虚拟地址空间)的局部变量以更改应用程序的行为。
address: in hexadecimal format, relative to the start of the process」s virtual address space
address:十六进制格式,相对于进程虚拟地址空间起始位置的偏移量。
however, running programs in a virtual address space has an associated cost.
然而,在虚拟地址空间中运行程序也会带来相应的成本。
shared memory allows multiple processes to map a portion of their virtual address to a common memory region.
共享内存允许多个进程将它们的部分虚地址映射到一个公用的内存区域。
this mechanism is often referred to as virtual memory and virtual address spaces.
该机制通常称为虚拟内存和虚拟地址空间。
in windows, you can use createthread() to create a thread to execute under the virtual address space of the calling process.
在windows 中,您可以使用createthread()来创建线程,创建的线程在调用进程的虚拟地址空间中运行。
mapping is a mathematical term for one-to-one correspondence -- memory is 「mapped」 when its virtual address has a corresponding physical location to store it in.
映射是一个表示一一对应关系的数学术语 ——当内存的虚拟地址有一个对应的物理地址来存储内存内容时,该内存将被映射。
on other platforms, you need to use the operating system imposed virtual address space size.
在其他平台上,需要使用操作系统决定的虚拟地址空间大小。
the number of page table entries is proportional to the size of virtual address space.
页表的数量与虚拟地址空间的大小成比例。
for 32-bit kernels, there are 4gb virtual address spaces.
对32-位内核而言,有4gb虚地址空间。
when running on a system with more process address space than physical memory, a memory leak or excessive use of native memory will force the os to swap out some of the virtual address space.
在进程地址空间大于物理内存的系统中,内存泄漏或本机内存过度使用会迫使操作系统提供一些虚拟地址空间。
available virtual address space.

for a variety of reasons, most modern operating systems run programs in virtual address space.
由于各种各样的原因,大多数现代操作系统都是在虚拟地址空间中运行程序的。
a dma request always involves moving data between the spe local store and a virtual address space on the ppe side.
dma请求通常会涉及数据在spe本地存储与ppe端虚拟地址空间之间进行移动。
on aix a process is a collection of information about os-controlled resources (such as file and socket information), a virtual address space, and at least one thread of execution.
在aix 上,进程是关于os控制资源(比如文件和套接字信息)、虚拟地址空间以及至少一个执行线程的一系列信息。
each guest operating system is mapped through the /dev/kvm device, having its own virtual address space that is mapped into the host kernel「s physical address space.
