                 Key: CLOUDSTACK-5713
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-5713

            Priority: Critical


env:4.3,kvm
steps:
1. create a advanced zone and add a host
2. deploy 2 vms
3. from host stop the vm 
4. check the vm state in Cloudstack

actual result:
