    Hi @wilderrodrigues 
    
    To test this you would need to have 2 or more cloudstack management servers operating
in a cluster with Xen hosts. Before applying this fix, when you try to live migrate vm's between
hosts (root disks on local storage or primary storage), occasionally this will fail. It is
random depending on which management servers are allocated the job. 
    
    After applying the change in the pull request, migrations should no longer fail. 
    
    Hope that is ok. 
    
    Thanks!
