Hi,

I can't start my virtual Windows 7 (32bit). Ubuntu 11.04 (64bit) is the host machine. Windows starts until the logo four colours shows up "deep in the screen". Then VirualBox closes itself. I have attached log file. Another machine, Ubuntu 12.04 (32bit), works fine.
Please help.

I see nothing in the log. It shows that the VM runs for about 1min with no logged activity, then the log ends. So, there is nothing much to go on.

Most likely you experience a VM process crash. Could you try creating a core dump for it as described here?
Also try disabling 3D and 2D Video acceleration and see if it improves the situation in any way.

Thank you for help. I didn't used your clues finally.
The same time I had problem with Unity and xserver on Ubuntu and it resulted that I had to recover my system partition from backup. After this Virtualbox works correct, so hard to say what caused the problem but now I hope it will never repeat.

Greetings!
