Adhering to the "all-people-oriented" principle, I finally chose to look at the kernel's memory management from a userspace perspective. The first series of articles selected the topic of VM Run parameter
Details about the VM module in NodeJs and the NodeJsVM Module
What is a VM?
The VM module is the core module in NodeJS. It supports the require method and the operating mechanism of NodeJS. In some cases, we may also need to use the VM template to do some special things.

The core of a virtual machine is a disk image, which can be understood as the disk of a virtual machine, which contains important files such as the operating system and driver of the virtual machine. This document de
Virtual Machine software can be used to simulate several computers on one computer (this computer becomes the host computer). Each computer has its own hardware configuration and can install a separate operating system, it is independent of the host operating system restrictions and complementary interference, so that a computer can "simultaneously" have multiple operating systems and connect these operating systems into a network.The following is a graphic Tutorial:

After the windows vm in xenserver is installed, it can be started from the optical drive through xencenter settings, while the linux vm does not have such an option. You can solve this problem through the following command line:

Static Migration: it is also called regular Migration and Offline Migration (Offline Migration ). Migration from one physical machine to another when the VM is shut down or paused. Because the Virtual Machine file system is built on the virtual machine image, when the virtual machine is shut down, you only need to simply migrate the virtual machine image and the corresponding configuration file to another physical host; if you need to save the status

In the previous chapter I've explained how to create a Windows Server VM that installs SQL Server 2012.
In this chapter I will describe how to mount a disk on this VM.
When you see this, there are readers who might have questions: Why do you want to introduce the features of a mounted disk here? Here I first briefly introduce the concept:
In some existing systems, the system disk (such as C disk) operati

Before you turn on the virtual machine, share the folder by configuring the virtual machine. By configuring shared folders, Ubuntu can access the E:\Share directory under Windows by accessing the/mnt/hgfs/share directory. Where thelast level of directory Share in/mnt/hgfs/share is the name in the configuration, Share in E:\Share is the host path configured in. 2. For example
