------------------------------------------

             Summary: not able to deployVM on kvm due to checking and stopping dom as part of does dom already exists check
                 Key: CLOUDSTACK-4011
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4011
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: KVM, Storage Controller
    Affects Versions: 4.2.0
         Environment: KVM, advance zone
ZWPS
            Reporter: Rajesh Battala
            Priority: Blocker
             Fix For: 4.2.0


While deploying the instance in KVM,
its checking whether the dom is already present or not by searching the dom and trying to stop it. 
As the dom is not present, its throwing the below exception and deploy is failing. 
I guess it good to check if the dom is present by lookup and continue further instead of stopping a dom which is not present which will definitely throw an exception and deploy fails
