So why are you saying "I am using und it does not work here" above?

halted state is not the way to check for whether cpu is online or
offline. cpu may be online but executing hlt instruction so
its state will be halted, but cpu itself is online. Actually with kvm
today you are not able to check that cpu is offline if it was ever
online. Query a guest for cpu status.
