Add a raw disk to a virtualbox virtual machine

VirtualBox 使用實體的硬碟
找出硬碟的位置如 /dev/sdb

$ sudo groupadd win10disk
$ sudo usermod -a -G win10disk youruser
$ sudo udevadm info /dev/sdX | grep UUID
E: ID_PART_TABLE_UUID=01234567-89ab-cdef-0123-456789abcde
$ vi /etc/udev/rules.d/99-win10disk.rules
ENV{ID_PART_TABLE_UUID}=="1234567-89ab-cdef-0123-456789abcde", GROUP="win10disk"
$ ls -l /dev/sdb
brw-rw---- 1 root win10disk 8, 16 Nov 4 23:33 /dev/sdb
$ VBoxManage internalcommands createrawvmdk -filename /path/to/diskname.vmdk -rawdisk /dev/sdb
