I am running Windows 7 64-bit and recently installed VirtualBox on which I installed Ubuntu 11.10 64-bit guest OS.

Everything runs smoothly until I found that I am not able to shutdown or reboot the virtual machine in a normal way (from within the guest OS). Whenever I do so, it just goes back to the login screen.

I have to use the VirtualBox's menu to force a shutdown. Has anyone experienced this before?

Thanks in advance!

Can you clarify "The normal way"?

Have you tried running:

sudo reboot

or

sudo init 0

from the terminal window within the guest OS? If so could you post what happens?

shutdown -P now, shutdown -h now, poweroff, halt -p, ... –  tyblu Dec 16 '11 at 18:02
    
@tyblu I assume there is a sudo prepended for all these commands. But there is a bug that has been confirmed for 11.10. bugs.launchpad.net/ubuntu/+bug/882817 –  Karlson Dec 16 '11 at 18:15
    
Hi Karlson, by normal way I mean clicking on the "Gear button" on the top right corner and select "Shutdown" and then either "Shutdown" or "Restart" brings me to the login screen. Yes I have tried "sudo reboot", same problem. –  airfang Dec 20 '11 at 7:28
