From the other thread it seems to me that there is a problem with the configuration file (?) ~/.VirtualBox/VirtualBox.xml which is empty.

Can you try to run the following command from a terminal

rm ~/.VirtualBox/VirtualBox.xml

After that try to start Virtualbox again and post the output.

****I have manage to capture the message which is below**** this happen when i execute vbox how can i go resolve this???

The virtual machine execution may run into an error condition as described below. We suggest that you take an appropriate action to avert the error.
The medium '/home/amadeus/.VirtualBox/Machines/WinXP/Snapshots/{06b85b38-ecdf-4fb4-82b6-acbbe3265fdc}.vdi' has a logical size of 2047GB but the file system the medium is located on can only handle files up to 2043GB in theory.
We strongly recommend to put all your virtual disk images and the snapshot folder onto a proper file system (e.g. ext3) with a sufficient size.

I am not sure how to proceed with that one, since I do not have practical experience with these details on Virtualbox. Still I think I can shed some light on the background.

For using a hard disk (or other storage media like memory sticks) you have to create a file system on it (equivalent to the term 'formatting' on Windows). There are several different file system structures defined, and Linux (e.g. Ubuntu) can work with several different ones. Just to name a few: MS-DOS file system, NTFS, ext2, ext3. Each of these file system has a defined maximum size that a single file on a device with that file system can have.

Ther error message above indicates that you are running against that maximum file size limit.

Possible solutions:
1. reduce the (maximum) size of you snapshot (affects virtualbox only)
2. use another file system that can hold bigger files (affect your whole Ubuntu installation)

I recommend to ask the experts on forums.virtualbox.org if they can help with your error message.

Did you install virtual disks on a Windows partition ?
If not, on which type of partition is installed your virtual disks ?

http://en.wikipedia.org/wiki/FAT32#FAT32 Max volume size 2 TB
You asked ti virtual box to make a virtual disk, whose potential size is bigger that managed size of FAT32 partition. So one day you could reach limit of partition before reaching limit of virtual disk, which is unhealthy. So follow Manfred's advices: reduce size of virtual disk (2TB is a huge size) or move virtual disk on another file system like Unix one or NTFS.
