Piers, I'm guessing you've been creating a Basic Networking Zone as the default wizard sends you in that direction.
If you have limited public IPs, and also want to leverage the full power of CloudStack you should create an Advanced network zone. This will give you private guest networks with a Virtual Router. Guest VMs will have private IPs and the VR will have a Public IP. If you need some VMs to have a Public IP directly assigned you can also create a Shared Network and allocate it a Public IP Range. There are some great blog articles on http://www.shapeblue.com which will help you understand the options etc. We also offer training sessions, again details are on the web site.

We only have a /27 at this stage and there are some other servers in use already. After using the CentOS set up guide a few times we could get things going but that basically used up our range or caused other problems [1]. Ideally I would like to generate private ranges for the VM guests and attach them to public IP's as required (something I am under the impression that Cloudstack can do ). Please bear in mind I have done the initial set up many, many times but with slight differences in selections trying to achieve this but run into road blocks. This time I have ignored the auto set up and created a zone manually. This has given me a set up with: cloud0 Link encap:Ethernet HWaddr inet addr:169.254.0.1 Bcast:169.254.255.255 Mask:255.255.0.0 cloudbr0 Link encap:Ethernet HWaddr 00:30:48:FC:6B:B4 inet addr: X.X.X.X Bcast:X.X.X.0 Mask:255.255.255.224 eth0 (is the bridged physical interface) Does my cloudbr0 having a public IP mean that I have to do something different to the install process? Is cloud0 a remnant of previous set ups or can/should the local guest network hang in this range? I'm not looking for someone to spoon feed me the answers (because I need to maintain this set up myself) but I feel like I have misunderstood something crucial. The install or set up pointers I am after is to achieve: X.X.X.X is a public IP with a NFS server on it (single machine set up). I want the management & storage networks to be virtual and private. I want to be able to allocate X.X.X.17 -> VM (169.254.0.26). [1] The CentOS how to points at every VM being on the same {public} range as the host. When set up this way the SSVM's were reported to contribute in a DNS DDoS. Sorry for all the typing but I am keen to learn more.
