Vagrantで作成したVirtualBoxで仮想ディスクサイズを変更する方法
0) 事前確認
VirtualBoxでvmdkファイルの場所を確認しておく。（下図を参照）
今回は、「 C:\Users(user)\VirtualBox VMs\Vagrant_default_1506839927322_11696\box-disk001.vmdk 」とする。
1) vmdkファイルからvdiファイルにクローンする
"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" clonehd "C:\Users\(user)\VirtualBox VMs\Vagrant_default_1506839927322_11696\box-disk001.vmdk" "C:\Users\(user)\VirtualBox VMs\Vagrant_default_1506839927322_11696\clone.vdi" --format vdi
2) vdiファイルのサイズを圧縮する
"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" modifyhd "C:\Users\(user)\VirtualBox VMs\Vagrant_default_1506839927322_11696\clone.vdi" compact
3) サイズを変更する(150GBに変更)
"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" modifyhd "C:\Users\(user)\VirtualBox VMs\Vagrant_default_1506839927322_11696\clone.vdi" --resize 153600
4) vdiファイルからvmdkファイルにクローンし直す
※vmdkファイルは、box-disk001_clone.vmdkとする。
"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" clonehd "C:\Users\(user)\VirtualBox VMs\Vagrant_default_1506839927322_11696\clone.vdi" "C:\Users\(user)\VirtualBox VMs\Vagrant_default_1506839927322_11696\box-disk001_clone.vmdk" --format vmdk
5) VirtualBoxでクローンしたディスクに付け替える
6) VM内でディスク設定

The partition table has been altered!
Calling ioctl() to re-read partition table.

The kernel still uses the old table. The new table will be used at
