Hi all,
we have installed a cloudstack 4.3.0 in advanced network mode on ubuntu
systems with only kvm hypervisor.
Today we received these series of notification (email):
1) Host disconnected, name: agent_name (id:7), availability zone:
zone_name, pod: pod_name
2) Host is down, name: agent_name (id:7), availability zone:
zone_name, pod: pod_name
3) Host disconnected, name: agent_name (id:7), availability zone:
zone_name, pod: pod_name
4) Host is down, name: agent_name (id:7), availability zone:
zone_name, pod: pod_name
5) Unable to restart vm_name which was running on host name:
agent_name(id:7), availability zone: zone_name, pod: pod_name
The server agent was not shut down nor rebooted and the virtual machines
are still running.
In agent log I found messages like these:
2015-01-26 15:04:40,728 INFO [cloud.agent.Agent] (Agent-Handler-2:null)
Cannot connect because we still have 5 commands in progress.
2015-01-26 15:04:45,729 INFO [cloud.agent.Agent] (Agent-Handler-2:null)
Lost connection to the server. Dealing with the remaining commands...

2015-01-26 15:04:50,729 INFO [cloud.agent.Agent] (Agent-Handler-2:null)

I tried to restart the agent service and after some minutes the log says:
2015-01-26 15:05:42,207 INFO [utils.nio.NioClient]
(Agent-Selector:null) Connecting to manager_ip:8250
2015-01-26 15:05:42,489 INFO [utils.nio.NioClient]

2015-01-26 15:05:42,489 INFO [utils.nio.NioClient]
(Agent-Selector:null) Connected to manager_ip:8250
But in manager interface I see this agent in Alert state.
Any idea to resolve this problem?
