Using:

$ VBoxManage internalcommands converttoraw Vivid.vdi vivid.img
Converting image "Vivid.vdi" with size 11212398592 bytes (10693MB) to raw...

The image is:

~/VirtualBox VMs/Vivid$ fdisk -l vivid.img

Disk vivid.img: 11.2 GB, 11212398592 bytes
255 heads, 63 sectors/track, 1363 cylinders, total 21899216 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x076ecf00

    Device Boot      Start         End      Blocks   Id  System
vivid.img1   *        2048    13512703     6755328   83  Linux

vivid.img5        13514752    21897215     4191232   82  Linux swap / Solaris

2) Mount

How to: http://www.linuxquestions.org/questi...g-file-882386/

The offset is: 512 * 2048 = 1048576

Mounting with the command:

sudo mount -o loop,offset=1048576  '/home/madprophet/VirtualBox VMs/Vivid/vivid.img' /media/iso

and the '/media/iso' has the virtual installation root directory mounted.




3) Copy

The new root and home - information from command: 'sudo blkid':

/dev/sda5: LABEL="AlphaRoot" UUID="ac1ecde9-89b0-4c82-8a15-2aa76b4c5ac2" TYPE="ext4" 
/dev/sda6: LABEL="AlphaHome" UUID="f3b54d9e-71e8-4978-8ea5-fa7da854df52" TYPE="ext4"

Mounting the /dev/sda5 (with Dolphin) to '/media/AlphaRoot/'

Copying with the rsync - 'a fast, versatile, remote (and local) file-copying tool':

sudo rsync -P -a /media/iso/ /media/AlphaRoot

4) Fix

The installation needs fixing - Few places has the information from the virtual installation:

- fstab
- grub
- old home directory


(/media/AlphaRoot)/etc/fstab

Old:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda1 during installation
UUID=e668a592-7f03-4250-a537-a1ef79c0cead /               ext4    errors=remount-ro 0       1
# swap was on /dev/sda5 during installation
UUID=8c9c12ff-7e00-4bab-87d4-fe124a15d59a none            swap    sw              0       0

New (UUid's from the sudo blkid):

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

UUID=f3b54d9e-71e8-4978-8ea5-fa7da854df52 /home           ext4    defaults        0       2

UUID=6374569b-646c-45c7-9e09-35c72e20e10d /media/sda2     ext4    defaults        0       2
# /media/sda3 was on /dev/sda3 during installation
UUID=bc02b2ec-13fb-448b-83b5-d497010b5f7c /media/sda3     ext4    defaults        0       2
# swap was on /dev/sda13 during installation
UUID=72c5fe1d-19c0-48eb-8913-e636764e92ee none            swap    sw              0       0

and removing the old home directory.


(/media/AlphaRoot)/boot/grub/grub.cfg

Changing (kwrite/kate find&replace) the root uuid from e668a592-7f03-4250-a537-a1ef79c0cead to ac1ecde9-89b0-4c82-8a15-2aa76b4c5ac2 - 23 replacements made.

Updating the local (trusty) grub:

sudo update-grub

This will read the information from the 15.04 grub to the local (trusty) /boot/grub/grub.cfg.
