             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Management Server
    Affects Versions: 4.3.0
         Environment: Build from 4.3
            Reporter: Sangeetha Hariharan
            Priority: Critical
             Fix For: 4.3.0


kvm - HA is not triggered when host is powered down since the host gets into "Disconnected" state.

Advanced zone with  2 KVM (RHEL 6.3) hosts.

Steps to reproduce the problem:
Deploy few Vms in each of the hosts .
Power down one of the hosts ( using IPMI).
We see that the host gets into "Disconnected" state.

All the Vms that are running in this host continue to be in "Up" state.

This happens because of management server receiving a explicit shutdown request from the agent:
