File vdsm/virt/vmchannels.py:

Line 55:             if fileno in self._channels:
Line 56:                 reconnect = True
Line 57:             else:
Line 58:                 self.log.debug("Received %.08X. On fd removed by 
epoll.",
Line 59:                                event)
> Maybe this then should be upgraded to 'error'? What happens when we are not
Actually this is not an error either. It won't cause harm to the inner 
workings. 

If this one happens, we cannot reconnect anyway since we're not tracking this 
fd anymore. (since it's not in self._channels)

This is a log message for post mortem checks to the logs if this happens when a 
customer/user had this issue. However this should occur very rarely, if at all 
now.
Line 60:         elif (event & select.EPOLLIN):
Line 61:             obj = self._channels.get(fileno, None)
Line 62:             if obj:
Line 63:                 obj['reconnects'] = 0
