Rohit Yadav created CLOUDSTACK-8530:
---------------------------------------

             Summary: KVM hosts without active agent connection are still "Up"
                 Key: CLOUDSTACK-8530
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8530
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: KVM
            Reporter: Rohit Yadav
            Assignee: Rohit Yadav
             Fix For: 4.6.0, 4.5.2


KVM hosts without active agent connection are still "Up". In case a KVM host get uncleanly
disconnected from the mgmt server, for example due to a firewall rule or physical nic unplugging
the neighbour KVM hosts might investigate and report that the KVM host is in Up state but
since mgmt server is not connected to the agent (on that host), all further commands such
as VM migrations, VM deployments etc fail. 

The best fix would be to have the investigator check the KVM host itself and if it's unable
to contact return the state as disconnected, this way no HA for VMs will be triggered.
