Bug Description

When I host is shutdown the state of the guest running on the host is "running".

1. When everything is up and running

localadmin@nova-host:~/nova$ euca-describe-instances
RESERVATION r-9nwcpyy9 proj default
INSTANCE i-0000002b ami-00000002 192.168.0.3

localadmin@nova-host:~/nova$

2. Shutdown nova-host (you can see that the host is down but the
instance is still up and "running") localadmin@nova-manage:~
localadmin@nova-manage:~$ euca-describe-availability-zones verbose

Hi,

In Essex, I am unable to find nova-host service.

Can you please guide me for nova-host installation?

I think this is pretty much just expected behavior. As far as nova is concerned, the instance is still at least supposed to be running. It may just be that the compute node has lost contact with the API temporarily but the VM is still running. Some additional action is required to tell nova otherwise.
