〖Linux〗VirtualBox修改虚拟电脑硬盘(vdi)空间大小

1. 查看需要修改的虚拟硬盘：

[scue@Link:tftpserver]$ vboxmanage list hdds
UUID:        79d65850-6846-40c3-a8e7-715b199d1673
Parent UUID: base
Format:      VDI
Location:    /media/Source/VirtualBox/Fedora9.vdi
State:       locked write
Type:        normal
Usage:       Fedora9 (UUID: b43e3dd0-60f3-4054-aa98-a5a0b354e2fe)

UUID:        422d3782-4818-47d7-8d03-0e86325572a0
Parent UUID: base
Format:      VDI
Location:    /media/Source/VirtualBox/WinXP3.vdi
State:       created
Type:        normal
Usage:       WinXP3 (UUID: 42a43120-581e-4a66-aa59-e79c0c43ac3a)
UUID:        492fec45-2508-4779-92c8-12a6949fa4d6
Parent UUID: base
Format:      VDI
Location:    /media/Source/VirtualBox/Ubuntu.vdi

Type:        normal
Usage:       Ubuntu (UUID: cf694a64-bd73-4759-9334-c602a2839db2)

 2. 假定需要修改的是 /media/Source/VirtualBox/WinXP3.vdi，UUID是 422d3782-4818-47d7-8d03-0e86325572a0：

[scue@Link:tftpserver]$ vboxmanage modifyhd 422d3782-4818-47d7-8d03-0e86325572a0 --resize $((40*1024))
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%

　>>然后就完成了（超级简单，无痛无害，不需要备份Snapshots什么）

3. 测试结果：
