Hi Lohit,

It's not immediately clear what the problem is, but I will venture a guess
that this error is being caused by a missing or incorrect library
dependency.

ConductorManager._keepalive_evt is created in ironic/conductor/manager.py at

 192     def init_host(self):
 ...
 222         # Spawn a dedicated greenthread for the keepalive
 223         try:
 224             self._keepalive_evt = threading.Event()

If that fails, it will call del_host(), which is where you're seeing the
traceback come from.

Hope that helps,
Devananda
