What you guys say about it. I'm using open-stack at scale and automated everything using there sdk(python-based). Now I'm thinking to properly move to xcp-ng and use its apis(rest+json-rpc) for automating the process. What will you say about it? I need your suggestions on it?
What will you say on virtualization and public cloud? Can we make it to work like a public cloud.
@olivierlambert Yes, Vates is on another level of professionalism. Wow 
@olivierlambert as shared earlier by @julien-f on this thread that we can only create vm on pool level and @olivierlambert said XO will automatically pick the host which has sufficient resources available for that vm. Can we manually pick the host in the pool to deploy a vm?
@DustinB If I add 20 hosts to a pool and create a VM in that pool, will it automatically pick the host that has sufficient resources available, such as CPU and RAM?
xcp-ng is a distribution which runs on a bare-metal and allow us to perform virtualization. I want to know more about hosts, pools. What is the difference between these two concepts. Also what is cluster and What about HA? Where does the HA happen? b/w pools or b/w hosts?
@Danp For now I'm going with JSON-RPC for only VM creation and for listings I'm using rest-apis. When XO6 will release I'll change the endpoint with rest endpoint. @olivierlambert any expected release date for XO6?
@olivierlambert omg 
I'll upgrade the XO. My question is still same, why the rest-api is not responding properly when I hit it from postman and the same api is responding with error when using xo-cli 
@olivierlambert Thank you for your time. I've a paid subscription but I am using XO from sources. I've opened a ticket from the help desk 
@Danp said in XO Rest API:
Is your VM up-to-date with the latest sources?
Yes I configured the XO from sources and it's not up to date. Should I update my XO and will it fix the issue or not?

@Danp for now I'm hitting cli for testing. This is the response im getting rn. The error is saying that the template doesn't exists in the pool, right? Also shared json-object is not giving the right response in postman.

This is the JSON-RPC send request and it's is using the same template which I'm using in above postman api call. If I pass all the params of JSON-RPC in
pools/_/actions/create_vm does it support all the payload? Actually I want to create the VM programmatically.
@julien-f I'm hitting the api in postman and this is the response i'm getting from the endpoint. My Pool is active and the template also is available. Can you please help me to solve this issue. Thank you.
@julien-f yes it is working, But when i pass the params as per shared in json-schema then nothing happens, no vm creation happens.

where to pass cpu and disk variables in the payload? Is there any payload example which I used for the rest-api? Is the http method is POST or PUT?
Hi @julien-f,
Thank you for your efforts in creating the REST endpoints. I want to create VMs using the REST API of XO, but I need a little help in this regard. Could you please provide the endpoint or the request structure for creating VMs?
My connection is working perfectly fine.
