             Fix For: 4.1.0


Ipv6 - Provide better error messages when deploying a Vm with Ip an address that is outside the network's ip range / if the ip address already is assigned to another Vm. 

Steps to reproduce the problem:

Create a Ipv6 shared network.

As a regular user , try to deploy a VM by passing a Ipv6 address that is already assigned to another Vm.

Api call fails with "errorcode":530,"errortext":"Internal error executing command, please contact your system administrator""

As a regular user , try to deploy a VM by passing a Ipv6 address that is not in the ip range of the network.

Api call fails with "errorcode":530,"errortext":"Internal error executing command, please contact your system administrator""

Expected Behavior:

In both the above cases , User should be presented with better error messages which will enable him to take corrective actions:

Note : When admin user does the above actions,  he is presented with more informative error message.
