I've installed Ubuntu 12.04 x64 (server) on my ESXi 5.0U1 server and it's mostly working fine except when I try to turn off the system using the halt command (/sbin/halt) it says "Powering off..." but the virtual machine never actually turns off.
If I use the VMware tools to shutdown the host it does turn off, but /sbin/halt worked in every other Ubuntu version and also works in Debian so it should work now...
Anybody have any suggestions?
