creating VMDK file for raw disk access by virtualbox on linux host

Posted 05-19-2014 at 04:32 PM by dr_agon

Recently I repartitioned my harddrive and had to recreate VMDK file which is used to access some of my physical partitions by guest machine.
You can do it using the command
$ sudo vboxmanage internalcommands createrawvmdk -filename test.vmdk -rawdisk /dev/sda -partitions 1,3
The result did not satisfy me, because guest machine required RW access to entire /dev/sda.
Looking for description of VMDK format I have found this.
So, I modified the lines in VMDK file replacing /dev/sda by /dev/sda1 and sda3 respectively, and removed the offset.
original line:
RW 61432497 FLAT "/dev/sda" 63
new line:
RW 61432497 FLAT "/dev/sda1"
Now I can grant RW permissions only to selected partitions (I described it in my earlier blog).
