Simple answer - you can't. In an advanced zone, you can specify the IP address when you create a new VM using the API, however in a basic zone, because the IP will depend on which POD your VM ends up in, and as a user you cannot influence this, there is no way to specific the IP, even if you are a root admin.
The reason it still fails when you manually change the IP is that the security groups feature is expecting the VM to have the IP CloudStack allocated it via DHCP.

If I want to: 1.allocate a specific ip to the vm. 2.allocate multiple ips to the vm. 3.change the vm ip from one to another. How can I achieve it?
