Just want to say something in defence of cloud providers - sometimes you need to limit the list of available CPU features to allow live migration between different hypervisors - even if you migrate the virtual machine to the latest state of the art CPU, /proc/cpuinfo won't reflect it (linux would go crazy if you tried to switch the CPU information on the fly) (the frequency boost would be measurable though, just not via /proc/cpuinfo )
