VirtualBox 重要的配置文件和配置程序

标签：virtualbox   配置文件   实用程序   

之前我安装了VirtualBox 来跑 Linux 虚拟机, 开始设置的时候设了 4G 内存, 结果后来不能改了. 造成的结果就是一开机, 内存飙到40%, 一开VirtualBox, 直接飙到95%. 然后开个数据库开个EBS 服务, 基本就不用干其他事情了.

怎么修改VirtualBox 虚拟机的内存分配呢? 有一个实用程序可以直接修改:

cd C:\Program Files\VirtualBox
VBoxManage.exe modifyvm "EBS R12 RUP8" --memory "2048"

那么这个程序修改了什么呢? 我们可以去看看下面两个配置文件;

1. 在User 目录下, 有个不可见目录 .VirtualBox, 里面有两个文件比较重要: VirtualBox.xml 和 VirtualBox.xml-prev. 后面一个是备份文件, 可以不用管他, 前面一个我们可以看看里面的内容:

<?xml version="1.0"?>
<!--
** DO NOT EDIT THIS FILE.
** If you make changes to this file while any VirtualBox related application
** is running, your changes will be overwritten later, without taking effect.
** Use VBoxManage or the VirtualBox Manager GUI to make changes.

在这个配置文件里面

    <Hardware version="2">
      <CPU count="2" executionCap="90" hotplug="false">
        <HardwareVirtEx enabled="true"/>
        <HardwareVirtExNestedPaging enabled="true"/>

        <Order position="2" device="DVD"/>
        <Order position="3" device="HardDisk"/>
        <Order position="4" device="None"/>
...

也可以直接修改这个文件, 但是文件注释告诉我们不要手动修改. 所以还是老老实实用程序或者通过界面修改吧;
