API: How to create a volume for qemu/kvm?

[ArtemZ]

Hello,
I found official proxmox api docs (http://pve.proxmox.com/pve2-api-doc/) to be completely unclear on how to create a qcow/raw volume for qemu/kvm VM and assign one to it (or how to specify that a volume should be created on VM creation) and how to specify extra options for this volume (read/write limits),
Could someone explain please?

Thanks

you need to look in doc pour qemu config update

PUT /api2/json/nodes/{node}/qemu/{vmid}/config

Note that proxmox gui use the api, so if you have firebug by example, you can see the ajax request to the api with parameters

I checked it before. It's not specific on KVM VM creation options.

I also checked Java and PHP API clients. Neither implements functionality for qemu/kvm virtual machine creation.

Documentation for PUT /api2/json/nodes/{node}/qemu/{vmid}/config doesn't describe volume creation. There are only two parameters related to my question: sata[n] and virtio[n]. Both, in my understanding, only allows to specify already existing volume and comments for both doesn't describe how to specify extra io management parameters.

There is a special syntax for colume creation, where you can pas the size in GB: example "-ide0 5"
