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?
EDIT: After further testing, "halt -p", "shutdown -h now", and "poweroff" all correctly power-off the machine but "halt" (without parameters) does not. However, in Ubuntu 10.04, "halt" did power-off the machine. Is this simply a difference between the two versions of Ubuntu?
