ubuntu 7.04 on VirtualBox

[Christian Buhtz]

I tried to install ubuntu-7.04-desktop-i386.iso on a VirtualBox machine 
with WinXP as host machine.

The install cd starts and I select "install". Then the ubuntu logo with 
the orange progress bar is shown. After some seconds my own physical pc 
(not the virtualbox machine!) make a "reset".

There is no freez, no error message. It is just as I would press the 
reset button on my physical machine.

Did anyone tried to install ubuntu on VirutalBox?
