Public bug reported: If an operator configures cpu0 in the dedicated set and enables state management, nova-compute will fail on startup with this obscure error:
Oct 06 20:08:43.195137 np0035436890 nova-compute[104711]: ERROR oslo_service.service nova.exception.FileNotFound: File /sys/devices/system/cpu/cpu0/online could not be found. The problem is that cpu0 is not hot-pluggable and thus has no online knob. Nova should log a better error message in this case, at least. ** Affects: nova Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
