Description

Trying to create a raw disk from my Windows XP partition to work on a Linux Guest OS and following the instructions posted on the forum from people that succeed doing the same thing I am trying ( http://forums.virtualbox.org/viewtopic.php?p=25200), after solving some pre-req issues, I end up with this error that people told me to open a new ticket here:

First, some info about the environment: Ubuntu Hardy Heron 8.04

user@machine:~$ uname -a
Linux machine 2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42 UTC 2008 i686 GNU/Linux

user@machine:~$ fdisk -l /dev/sda

And now the createrawvmdk try:

user@machine:~$ sudo VBoxManage internalcommands createrawvmdk -filename /home/user/WinXPFromPart1.vmdk  -rawdisk /dev/sda -partitions 1 -mbr /home/user/fakeMBR.mbr

ERROR: VMDK: cannot go backwards for partitioning information in '/home/user/WinXPFromPart1.vmdk'
Error code VERR_INVALID_PARAMETER at /home/vbox/vbox-1.6.2/src/VBox/Devices/Storage/VmdkHDDCore.cpp(2518) in function int vmdkCreateRawImage(VMDKIMAGE*, VBOXHDDRAW*, uint64_t)
Error while creating the raw disk VMDK: VERR_INVALID_PARAMETER

It is really a bug or there is some other configuration to workaround the problem? Thanks in advance...

  • Component changed from other to virtual disk

comment:2 Changed 6 years ago by joebpimentel

As suggested by TerryE, (forum discussion: "createrawvmdk does not work":  http://forums.virtualbox.org/viewtopic.php?p=29178#29178), the following attempts are made trying to understand what is happening:

1:

VBoxManage internalcommands createrawvmdk -filename ~/.VirtualBox/WinXP.vmdk  -rawdisk /dev/sda -partitions 1

2:

VBoxManage internalcommands createrawvmdk -filename ~/.VirtualBox/WinXP.vmdk  -rawdisk /dev/sda

Quoting TerryE conclusions: "What this tells us is that (1) the MBR flag has nothing to be with the error and (2) the error path is excited by processing a partition list but not a whole disk. Can I suggest that you feed this data into the ticket."

Hope this helps...

Excuse-me, at the previous comment I forgot to tell that the first command (1) returns the same error while the second command (2) works but the created .vmdk could not boot into Windows XP. Tks.
