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!
