Booting from USB under virtualbox

List all disks:

$ diskutil list
[...]
/dev/disk2 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                        *8.0 GB     disk2

Change permission on USB disk:

chown user /dev/disk2

Create virtualbox raw device:

sudo VBoxManage internalcommands createrawvmdk -filename ./usbdisk1.vmdk -rawdisk /dev/disk2
sudo chown user ./usbdisk1.vmdk

Finally, add the disk under virtualbox.
