I work with Havana installation, one control host plus two nova-compute (libvirt with kvm). I'm trying to set up guest VM high availability solution - monitor host going down and do host-evacuate via API.

My problem is: even when I shutdown compute host, 'nova-manage service list' shows that this host state is up (not XXX, but smiley face). And, when in this state, host-evacuate command is not willing to be executed - it expects host to be in down state.

Maybe, somebody could give an advice - how to troubleshoot this situation and where to look?
