VBoxManage：错误：无法从“/dev/disk0”读取分区信息

Question

我正在尝试.vmdk为 Virtual Box创建一个分区文件。基本上我想在 Virtual Box 中启动我的 bootcamp 分区盒。但是当我尝试制作.vmdk文件时出现以下错误

VBoxManage: error: Cannot read the partition information from '/dev/disk0'
VBoxManage: error: The raw disk vmdk file was not created

这是我在终端中输入的命令的确切顺序

sudo chmod 0777 /dev/disk0

sudo chmod 0777 /dev/disk0s4

sudo VBoxManage internalcommands createrawvmdk -filename WinXP.vmdk -rawdisk /dev/disk0 -partitions 4

VBoxManage: error: Cannot read the partition information from '/dev/disk0'
VBoxManage: error: The raw disk vmdk file was not created
