>>Based on what I have read, I think I would like to setup a Public Cloud, essentially some hypervisors on a private network(lets say 10.1.254.0/24) and storage on another network(let's say10.1.253.0/24) and then all the VM's given public IP's(let's say 200.10.10.0/24). I don't understand how to do that, or even what the difference is between a Guest network and Public network(do they have to be separate?)
using this info how I'd setup this specific cloud in cloudstack is. have your public network on a vlan, say 200. trunk that down to your hosts. You'll also need a zone vlan range... 300-400. How these manifest in cloudstack is; whenever a user creates a vm on a guest isolated network, a vlan will be plucked from that range, and used to create an isolated network. whatever you defined as your guest cidr in the zone creation wizard. this is where your guests will reside. each account will have the same isolated network 'range' or segment, if theyre using the guest isolation method. a virtual router is created, with a leg on the public network, a leg on the guest isolated network and another private address( we wont worry about that for now). These dont impact your private networks since those should be separate from your virtual infra. from there your vm's public traffic will route out through the VR on its public leg. one can setup NAT rules to surface services setup on the guest vm's. Hopefully that gives you a better picture of how this fits together... feel free to ask more questions and file bugs on the docs!!! :) On Mon, Aug 12, 2013 at 1:10 AM, Mark van der Meulen <m...@fivenynes.com>wrote: > Hi, > > I am having a little trouble understanding how the cloudstack networking > model works, I have read the documentation and enquired on IRC(without > response) and still don't really get it.
