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

             Summary: DeployVM: automatically generated hostName is not RFC 
compliant
                 Key: CLOUDSTACK-4979
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4979
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
    Affects Versions: 4.2.0
            Reporter: Alena Prokharchyk
            Assignee: Kelven Yang
             Fix For: Future


When no hostName is passed in to the deployVM call, we generate random UUID. 
But this uuid is not compliant with RFC for the hostName as it always starts 
with the digit. Here are all the rules for the hostName:

 // must be between 1 and 63 characters long and may contain only the ASCII 
letters 'a' through 'z' (in a
        // case-insensitive manner),
        // the digits '0' through '9', and the hyphen ('-').
        // Can not start with a hyphen and digit, and must not end with a hyphen
        // If it's a host name, don't allow to start with digit
