Hello all and thank you in advance for your help. I have been able to work out how to add vm via a call to the vms API. I am passing in a template via the api call and that is working. I do not have a network installed in the template. My use case for that was to hit “New vm”, fill in the hostname and network and let cloud-init set the hostname. That way I can create a new vm with just a few clicks. What I can’t seem to figure out is how to define the network interface in the add vm api call. It looks like I should have to add the network interface in a second call after creation. If I add the interface in the <initialization> section for cloud-init I seems to have a chicken and egg problem. When I add the <initialization> section and the data for the ip address, netmask, default gateway, I get; <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <fault> <detail>[Cannot add VM. Static IPv4 address is missing in cloud-init configuration.]</detail> <reason>Operation Failed</reason> </fault> That would seem to indicate to me that I need and interface before I can configure it. That makes sense. But how do I get an interface before I create the vm ? What might I be missing? The desired result is create a vm and set the hostname and ip info via the api so that I get a fully formed vm connected to the network. That gets me to the point of being able to download build scripts to install and start puppet. Alan
