Here it is /dev/disk1, containing two partitions /dev/disk1s1 /dev/disk1s2 (one Windows and one Linux). Identify the disk to access with VirtualBox. I did more or less what you want: to access the disk in raw mode as Linux boot.

This is super useful for Macbooks when installing Arch Linux, because the default ISO does not load the wlan card drivers.

VirtualBox is finicky about where it looks for a boot file. If using grub-mkconfig, the name of the efi file is grubењ†4.efi (assuming 64 bits). This is not so obvious, especially if you use an EFI setup. a bootable linux ISO of your liking) and turn on the Live CD/DVD optional so that you boot from it. ( IMPORTANT ensure the drive has not been remounted, otherwise you will get VERR_RESOURCE_BUSY, NS_ERROR_FAILURE)ДЄdd an optical disk file (e.g. Select existing drive using VMDK created above.

Add New Machine, provide name: /dev/disk2, type: linux, version: arch linux (64-bit).

To confirm permissions of devices, you can run ls -l /dev/disk* If you open a file browser, you will see the root's home folder by default.ДЄnother option is to change the permissions of the device (not recommended) as you have done. Your other virtual machines will not be visible. Your home context (home folder and preferences) will be changed to root. Sudo /Applications/VirtualBox.app/Contents/MacOS/VirtualBoxД«ecause devices are all owned by root, you need to start VirtualBox with root privileges. Start Virtual Box Manager with Root Privileges a device might be assigned a different number especially if you unplug things and move things around. After reboot, the situation could change e.g. I use rdisk-disk2.vmdk for the name, because this virtual machine is just a pointer to this device. You may want to add an entry in fstab with the added parameters noauto to prevent the OS from remounting the drive. VBoxManage internalcommands createrawvmdk -filename '$HOME/dev-disk2.vmdk' -rawdisk /dev/disk2Д®ject the device before this step, otherwise you will get an error: VERR_RESOURCE_BUSY. 2, as in /dev/disk2 Assuming 2 for the rest of the instructions. I had a need to do this today and I saw your question, so here is a protocol of the steps I took. Now, when I start the linux guest OS, I get the FATAL: No bootable medium found! System halted. Also, /dev/disk0 is now readable from VBoxManage: $ VBoxManage internalcommands listpartitions -rawdisk /dev/disk0 Per the Froggard howto made it so I could add the image to a VM. Making myself the owner of the /dev/disk0 and /dev/disk0s2 with $ chown $USER /dev/disk0 Here, disk0 is the dedicated linux drive.

Since nothing shows up here for sectors or partitions, this must be a symptom of the problem.

So I am trying to set up raw device access w/ VirtualBox to use a ext4/linux disk as a guest OS within Mac OS X, but haven't succeeded yet.ДЇollowing the VirtualBox docs, Chapter 9.9.1.1, will Mac OS X allow raw disk access for VMs? How do I set this up?
