Subject Re: Adding secondary IP to VM
Date Wed, 11 Jul 2018 09:40:07 GMT
ACS doesn't handle this in any way (except that it might reserve the IP, so
it's not possible to add same IP to another VM/nic in same network).

You need to manually configure secondary IP on the VM - this is at least in
4.8 release, and per my experience so far.
