VBox: Attach physical disk to a virtualbox VM
Virtual Box does support attaching physical (raw) drives to a VM but there is no option for it in the GUI.
To attach a drive to a VM you will first need to install the Oracle VM VirtualBox Extension Pack available here:
After that is done you can create and attach a new virtual disk from the command line.
VBoxManage internalcommands createrawvmdk -filename /path/to/file.vmdk -rawdisk /dev/sdf
This creates the image /path/to/file.vmdk (must be absolute), and all data will be read and written from /dev/sdf.
Just like with regular disk images, this does not automatically attach the newly created image to a virtual machine.
This can be done with e.g.
VBoxManage storageattach <NAME> --storagectl "IDE Controller" --port 0 --device 0 --type hdd --medium /path/to/file.vmdk
See http://www.virtualbox.org/manual/ch09.html#idp13208480 for more details.
Change UUID of a disk:
VBoxManage internalcommands sethduuid disk_image.vdi
