Virtualbox Use Physical Disk

Posted: 

On 10.5.3 intel core 2 duo (macbook air). Installed Windows XP pro on a physical partition with NTFS file system. It boots fine directly but trying to use VBoxManage command, I first got VERRACCESSDENIED, so, looking into the device file in question, it had the group 'operator' on it, so I put my own user in 'operator' group, now the command succeeds. (although, like said above, specifying the -partition parameter fails with VERRDEVIOERROR, which means, I can't give more than 2 partitions access to the guest OS.)Now I do have a vmdk file created at specified location, but whenever I add a new virtual machine through the gui interface and tries to load it up, it now gives same 'VERRACCESSDENIED' even though the user can access the device now.Something is broken down here. I am running OSX Tiger with some of the same problems. Dmyurych's strategy works for me, though the permissions needn't be so open. Hi,sorry to use this bug report as a forum, but could anyone boot the bootcamp partition using this procedures?I could create the partition and boot it, but I'm stuck in:A disk read error occurredPress Ctrl+Alt+Del to restartThis commands worked for me:umount /Volumens/WinXPsudo VBoxManage internalcommands createrawvmdk -filename /Users/myusername/Library/VirtualBox/VDI/raw-disk.vmdk -rawdisk /dev/disk0s3 -registersudo chown myusername /Users/myusername/Library/VirtualBox/VDI/raw-disk.vmdksudo chgrp admin /dev/disk0s3sudo chmod 660 /dev/disk0s3Change myusername to your username.

Change disk0s3 to your partitionMany thanksOliver. Oliver - in my instance this workaround does not result in a bootable partition because the VB guest sees the partition as an entire disk, so in my case of Fedora 10, fedora writes an x86 bootsector to the 'drive', a partition map, and then the partition. My bootloader, rEFIt expects there to just be a bootable partition there, so it doesn't know what to do with all that extra stuff. I put in an RFE for rEFIt to be able to chainload this setup, but even better would be for this bug to be fixed so it's unnecessary.If anybody read my prior comment, please note that this page ate the backticks around whoami and that these perms need to be applied after each OSX boot, they get reset on boot.

How-to convert a (UEFI-based) Windows 10 physical installation into an Oracle VirtualBox guest. Virtualbox Use Physical Disk Free; Virtualbox Use. 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. Following the.

Fortunately the VB GUI will warn you in this case. OK, tracked it down. OSX is pretty paranoid about opening the devices, and the error code printed by virtualbox was very misleading (the original error code was EBUSY). In the first place one cannot open an entire disk for writing when one partition is mounted. There are probably ways around this (otherwise it'd be impossible to repartition), but it looks like they are not necessary.

After all it's good that people cannot shoot themselves into the foot.After applying a few small hacks to the current svn code I could create a raw partition vmdk (required changing the permissions of /dev/disk0s3 AND ejecting the volume) - and when I enabled IO-APIC in the VM settings booting the bootcamped Vista worked as expected.So either build the latest code yourself (should show up in the public svn soon) or wait for the next release. Hi klaus,I cannot achieve how to boot my physical Debian from Mac host.I've created the physical vmdk:VBoxManage internalcommands createrawvmdk -filename raw-disk-linux.vmdk -rawdisk /dev/disk0 -partitions 4,5(4: ext4 root, 5: swap)Now, when I try to boot, grub starts (so the MBR is here), but Linux recognize me only a /dev/hda with an unknown partition table.If I do fdisk -l, I can see the true partition table.Somehow the partitions are gone? Or is the virtual disk layout (CHS?) different from the physical disk that inhibit Linux to see them (and create device nodes)?I also tried to create the vmdk with -rawdisk /dev/disk0s4, and with Ubuntu Live I can mount it, but obviously there isn't any mbr/partition table on the partition itself for making it bootable.Thanks.ps: should I create a new ticket? The createrawvmdsk command works for sure, but isn't very useful to me:P. Same problem here.Using 3.0.4, with MacOSX 10.5.8, I've succeeded to create the VMDK files using VBoxManage, setup a VM and boot it.Grub launches but init stops after loading the kernel at mounting the root FS.The reason being 'sda: unknow partition table'After the few seconds delay, Busybox kicks in.cat /proc/partitions only reports /dev/sda.

No partition.I tried to provide a MBR. I guess the -pt.vmdk file is broken.It seems that on MacOSX hosts, only bootcamp'd vista is supported:-/.

Interwrite prs software download. Before this tickit is signed off as being complete, please note that there still seem to be problems in general when trying to setup a MacOS X bootcamp partition as a Guest with release 3.0.4. This despite some peoples success in setting up some Guest OSes. In my case, I have tried to setup a bootcamp partition containing Windows XP (SP2). I am able to setup the Virtual Machine using the prescribed VboxManage command line and setting RW permissions on the Unix devnodes for /dev/disk0 and /dev/disk0s3. This part of it was made to work with rev 3.0.4.

Raw

But when I attempt to start the Virtual Machine, I get the following message block in the Virtual Machine window:'Windows could not start because of a computer disk hardwareconfiguration problem.Could not read from the selected boot disk. Check boot pathand disk hardware.Please check the Windows documentation about hardware diskconfiguration and your hardware reference manuals foradditional information.' It has been about a year now since I discovered. I originally found it because I was contemplating buying vmware fusion and decided to look if there was an open source solution before I spent the money.

I found VBox and was pleased with what I saw. That is with the exception of the fact that I could not setup VBox on my existing bootcamp partition. I decided to use a regular VDI virtual machine while I was waiting for this to be fixed. I was encouraged when the 3.0.4 release came out, but was frustrated when it was discovered that this only fixed part of the problem.So, I guess my next question is can we get some priority on getting the general bootcamp partition running as a virtual machine working? I think I prematurely opened a new ticket, now that I better understand the current issue, I see that it is closely related to the original issue so that this ticket could be considered 'incomplete' or 'in progress'Following jerome's steps, I was able to use VMWare Fusion trial's vmware-rawdiskCreator (don't think it requires a current trial license) to create a working rawdisk-pt.vmdk. This util doesn't seem to support multiple partitions though, so I don't have access to the swap partition. I got this working finally.

I don't know if something was resolved between 3.0.4 and now (3.0.8) or if it was the change I did. Whatever it was, it's working.All I did was unmount the bootcamp drive, then type in terminal (my username is J),sudo chmod 777 /dev/disk0s3sudo VBoxManage internalcommands createrawvmdk -rawdisk /dev/disk0 -filename win7raw.vmdk -partitions 3sudo chown J.vmdkI then used virtualbox media manager to add the created vmdk to my list of harddrives. Then I added that to my virtual machine (settings, harddrives,add). I changed the IDE Controller Type to ICH6 (found that tip elsewhere regarding this issue).I also have updated bootcamp to 3.0 since this problem started.Maybe a combination of all these changes (or just one in particular) but now it boots fine! Hope this helps someone else.

Many users run into problems when it comes to attaching physical media to their virtual machines over USB. This guide will show you the simplest way to make it work.

Have you tried attaching a USB device to your VirtualBox virtual machine (VM) only to have it not show up as recognized? This is actually a very common issue and one that plagued me when I first started using VirtualBox. The problem is mainly that through VirtualBox plug’n’play doesn’t function properly and Windows is unable to figure out what driver the USB device needs. The way to fix it is to set up the proper filter in VirtualBox settings.

Mount Physical USB Drive VirtualBox

In order for mounted USB devices to function, the virtual machine must have Guest Additions installed. It’s incredibly easy to install these, just run the virtual machine and then from the host window select Device > Install Guest Additions… VirtualBox should load a virtual disk with the guest additions setup if it doesn’t run automatically just go into the virtual disk and launch the installer.

Now go back to the VirtualBox manager and right-click the VM that you want to use the USB device with to open the Settings window.

Within settings, browse to the USB tab and click the Add button on the very right of the window. Select the USB device that you wish to use from the list. Once done, click OK to save changes and exit.

Now go back into your VM window and from the Host options select Device > Usb Devices > “your usb device.”

The USB device should now show up just as it would on your physical computer. And that is all there is to adding a physical USB device to your VirtualBox VM’s.

If you have any questions, comments, or problems please check out the Troubleshooting section below and leave a comment further down.

Troubleshooting

Still not working? Try installing the Virtualbox Extension Pack. Just download it from Oracle and then run it to let Virtualbox automatically add it.

You may need to restart the computer and/or the virtual machine before the mounted USB device will work.
