    Thanks for the fix! 
    
    Although I think that after id=25 stuff breaks on KVM, as the code generates a deviceName that is invalid. Id 25 results in vdz, after that it continues with caracters like `{` etc. The default for KVM seems to be 32 (as defined here: https://github.com/apache/cloudstack/blob/87ef8137534fa798101f65c6691fcf71513ac978/setup/db/db/schema-452to460.sql#L422).
    
    See: https://github.com/apache/cloudstack/blob/master/plugins/hypervisors/kvm/src/com/cloud/hypervisor/kvm/resource/LibvirtVMDef.java#L591
    
    So we either limit it to 25, or improve the code to generate valid device names above id 25. What do you think?
