>As per previous code, vmNameOnVcenter = vmSpec.getHostName(), which will
introduce backward compatibility issues for older 4.3 environments. Is there
any code that handles for such old VMs.
Yes, vm.instancename.flag will handle backward compatibility issue.
Case (vm.instancename.flag = True):
User can create the VM with same name form different account.
Case (vm.instancename.flag = False):
User can not create the VM with same name form different account.
Note - But in both the cases, VM with same name are not allowed on a
particular network. And only for the User VM's name format will be like
"I-<user-id>-<Display-Name>" if "vm.instancename.flag = True". It will not
cause any impact on other VM names( like Router VM).
