    1. Advance zone  with 1 cluster with 2 hosts. Create  Shared network with private vlan. 2. Deploy few HA enabled Vms in this network. 3. pull network cable for one of the host. When cloudstack detects that the host is disconnected , it is not able to out the host in disconnected state and start HA for Vms that are HA enabeld, I see the following exception in the management
