I have the same problem on the latest build of Virtual Box v4.1.12. In both 11.10 and 12.04 beta2 I install Ubuntu Server x86 with nothing but the defaults selected and I get the following:
sudo shutdown now [sudo] password for xxx: Broadcast message from [user]@[server] (/dev/tty1) at 10:36 ... Skip stopping firewall: ufw (not enabled) * Asking all remaining processes to terminate... [ OK ] * Killing all remaining processes... [fail] * Will now switch to singler-user mode [user]@[server]:~# So matter how many times I run sudo shutdown now I get the exact same thing and the server never shuts down. I've tried several of the suggestions above, but given how simple my setup it, I would imagine it should be fairly easy to replicate this.

Sometimes the pc shuts down but ends with the ubuntu splash screen and gets stuck there. The issue may be driver related: I use the AMD/ATI FGLRX graphics driver. I have a second pc where I also did the update to 11.10 and there I have no problem at all but I don't use the above driver but the NVIDIA graphics driver. Both pc's have Ubuntu 11.10 64-bit.
