修改固定大小的 VDI 虚拟磁盘

修改固定大小的 VDI 虚拟磁盘 – Havee’s Space

空间紧张,故给 VirtualBox 下的 Windows 8.1 分配的虚拟磁盘是固定大小的 20GB,今天给 Windows 8.1 打补丁的时候,终于出现磁盘空间不足的警告了,不得不给虚拟磁盘扩容。

网上爬文,找到解决方法,是通过参数 modifyhd 来修改,记录下:

首先固定大小的虚拟磁盘是不能扩容的

/Users/cnhavee/Documents/Virtual Machines.localized/Windows 8.1 $ VBoxManage modifyhd Windows 8.1.vdi --resize 31480
0%...
Progress state: VBOX_E_NOT_SUPPORTED
VBoxManage: error: Resize hard disk operation for this format is not implemented yet!
/Users/cnhavee/Documents/Virtual Machines.localized/Windows 8.1 $ VBoxManage showhdinfo Windows 8.1.vdi

Format variant 为 fixed default,动手转化吧

/Users/cnhavee/Documents/Virtual Machines.localized/Windows 8.1 $ VBoxManage clonehd Windows 8.1.vdi ./Windows 8.1_clone.vdi
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%

UUID:           380da4bf-e8fd-40eb-884e-b6a3568739c6
Parent UUID:    base
State:          created
Type:           normal (base)
Location:       /Users/cnhavee/Documents/Virtual Machines.localized/Windows 8.1/Windows 8.1_clone.vdi
Storage format: VDI
Format variant: dynamic default

Size on disk:   20075 MBytes

好了,现在是 dynamic default,扩容

/Users/cnhavee/Documents/Virtual Machines.localized/Windows 8.1 $ VBoxManage modifyhd Windows 8.1_clone.vdi --resize 31480
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%
/Users/cnhavee/Documents/Virtual Machines.localized/Windows 8.1 $ VBoxManage showhdinfo Windows 8.1_clone.vdi
UUID:           380da4bf-e8fd-40eb-884e-b6a3568739c6
Parent UUID:    base
State:          created
Type:           normal (base)
Location:       /Users/cnhavee/Documents/Virtual Machines.localized/Windows 8.1/Windows 8.1_clone.vdi
Storage format: VDI
Format variant: dynamic default
Capacity:       31480 MBytes
Size on disk:   20075 MBytes

扩容成功,最后通过 VirtualBox 的界面,添加一块虚拟磁盘,定位为 Windows 8.1_clone.vdi,再移除旧的磁盘 Windows 8.1.vdi 即可。

当然,最后还得在虚拟 Windows 8.1 中,扩展下你的 C 盘,否则显示的还是 20GB。

顺带提一下如何压缩 VDI 磁盘,需要写零工具 SDelete:http://technet.microsoft.com/en-us/sysinternals/bb897443.aspx

下载下来的 sdelete.exe 放入 %system32% 下。

  1. 首先虚拟机下整理磁盘
  2. 打开 cmd(win7 以后需要管理员权限),sdelete -z
  3. VBoxManage modifyhd path|uuid --compact
