Subject RE: VM Instance ip difference beetween Network types

Antonio,

I guess the bit I can't understand is why is it a problem to have an IP allocated.

Guest IPs in an Advanced Zone are unique to their CIDR, are behind their Virtual Router, take
up no resources, and do not cost anything in real terms.

I can only guess that you are using a Shared Network with real Public IPs that you have a
limited supply of.

Regards

Geoff Higginbottom

Subject: Re: VM Instance ip difference beetween Network types

Geoff,

i try to explain you what happened and which is my target.

When i used basic network configuration, by API i send deployvirtualmachine command with startvm
set to false in according to:

http://cloudstack.apache.org/docs/api/apidocs-4.2/domain_admin/deployVirtualMachine.html

By doing this i was able to create configuration of a vm WITHOUT assign immediately an IP
address. This is much important for us.

This is my goal. Create vm config and NOT assign IP address immediately.

Instead, if i use advanced network configuration and same commands to API, IP address will
AUTOMATICALLY assigned to vm ( a sort of reservation of IP ).

I want avoid this because i do not want to have a situation where N customers can create vm
without using them and IP addresses will be reserved for them.

With basic network configuration i can do this. With advanced i can not.

Waiting for your reply

Best regards
