Oracle VM VirtualBox技巧

配置文件

Linux 虛擬機配置文件分為兩處。

windows下：
1、用戶名/.VirtualBox/
這里面有2個配置文件：
VirtualBox.xml 和 VirtualBox.xml-prev. 后面一個是備份文件, 可以不用管他, 前面一個我們可以看看里面的內容:

<?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.
-->
<VirtualBox xmlns="http://www.innotek.de/VirtualBox-settings" version="1.12-windows">
  <Global>
    <ExtraData>
      <ExtraDataItem name="GUI/DetailsPageBoxes" value="general,system,preview,display,storage,audio,network,usb,sharedFolders,description"/>
      <ExtraDataItem name="GUI/GroupDefinitions/" value="m=83d5321d-32f6-438b-b81c-3e336ccc1460,m=ef9627ae-2637-4f90-a9e9-1423fbdccbd1"/>
      <ExtraDataItem name="GUI/HostScreenSaverDisabled" value="false"/>
      <ExtraDataItem name="GUI/Input/AutoCapture" value="true"/>
      <ExtraDataItem name="GUI/Input/HostKeyCombination" value="163"/>
      <ExtraDataItem name="GUI/LastItemSelected" value="m=xp"/>
      <ExtraDataItem name="GUI/LastWindowPosition" value="298,89,770,550"/>
      <ExtraDataItem name="GUI/SplitterSizes" value="192,573"/>
      <ExtraDataItem name="GUI/SuppressMessages" value="confirmInputCapture"/>
    </ExtraData>
    <MachineRegistry>
      <MachineEntry uuid="{ef9627ae-2637-4f90-a9e9-1423fbdccbd1}" src="D:\VirtualBox VMs\xp\xp.vbox"/>
      <MachineEntry uuid="{55a1a18a-0cb6-4238-bcdb-2df5d647e255}" src="D:\VirtualBox VMs\centos\centos.vbox"/>
    </MachineRegistry>
    <MediaRegistry>
      <HardDisks/>
      <DVDImages/>
      <FloppyImages/>
    </MediaRegistry>
    <NetserviceRegistry>
      <DHCPServers>
        <DHCPServer networkName="HostInterfaceNetworking-VirtualBox Host-Only Ethernet Adapter" IPAddress="192.168.56.100" networkMask="255.255.255.0" lowerIP="192.168.56.101" upperIP="192.168.56.254" enabled="1"/>
      </DHCPServers>
    </NetserviceRegistry>
    <SystemProperties defaultMachineFolder="D:\VirtualBox VMs" defaultHardDiskFormat="VDI" VRDEAuthLibrary="VBoxAuth" webServiceAuthLibrary="VBoxAuth" LogHistoryCount="3" exclusiveHwVirt="false"/>
    <USBDeviceFilters/>
  </Global>
</VirtualBox>

注意此處定義虛擬機文件uuid及所在位置：

<MachineRegistry>
  <MachineEntry uuid="{ef9627ae-2637-4f90-a9e9-1423fbdccbd1}" src="D:\VirtualBox VMs\xp\xp.vbox"/>
  <MachineEntry uuid="{55a1a18a-0cb6-4238-bcdb-2df5d647e255}" src="D:\VirtualBox VMs\centos\centos.vbox"/>
</MachineRegistry>

其中uuid來自於src對應文件.vbox里面的：

<Machine uuid="{55a1a18a-0cb6-4238-bcdb-2df5d647e255}" name="centos" OSType="RedHat" snapshotFolder="Snapshots" lastStateChange="2015-12-02T14:16:08Z">

如果不小心重新重新安裝VirtualBox或者刪除了VirtualBox的配置文件，只要虛擬機沒有刪除（如.vbox、.vdi文件），可以重新安裝虛擬機后仿照MachineRegistry里MachineEntry添加一行。注意uuid不錯，必須和.vbox里的一致。

2、虛擬機目錄里的.vbox文件
這是個文本文件，可以直接編輯。例如：

<?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.
-->

以直接修改這個文件, 但是文件注釋告訴我們不要手動修改. 所以還是老老實實用程序或者通過界面修改吧。

CentOS 6.6 Minimal設置文件夾共享

安裝增強功能

需要先更新內核

yum clean all
yum install kernel-devel
yum install kernel-headers
yum install gcc
yum install make  
reboot

然后安裝增強功能：

mount -t auto /dev/cdrom /mnt
cd /mnt
sh ./VBoxLinuxAdditions.run

配置共享文件夾

打開 VirtualBox 界面，選擇對應的虛擬系統進行"設置"，選中設置窗口中的最后一項"共享文件夾"，再選中"固定分配"，右鍵單擊並確定共享文件夾的路徑，下面的復選框一個都不用勾選，最后"確定"。

啟動虛擬系統，進入系統以后，執行以下命令來掛載共享文件夾：mount -t vboxsf shared /mnt，其中 shared 為共享文件夾的名字，/mnt 表示當前掛載到 mnt 目錄下。如果需要取消掛載，可以直接使用命令：umount -f /mnt。

設置開機自動掛載：上述掛載方法只能起到臨時掛載的效果，無法做到每次開機自動掛載，如果想要實現自動掛載，可以在開機時執行掛載腳本：vi /etc/rc.d/rc.local，在文件的最后面加上掛載命令：mount -t vboxsf shared /mnt，這樣就可以實現每次開機時自動掛載共享文件夾了。
