[libvirt] xml format for openvz driver

Hello! I made review of domain XML format for driver in libvirt. And I have several questions and additions. For tag domain: need to add "vmid" or "id" - currenly tag "name" is used for ID. OpenVZ has mandatory parameter ID, but it also support optional parameter "name", which is not implemented for openvz driver now. I plan to support of "name" in future. For tag domain/os: need to add "ostemplate" desirable "config" For tag domain/devices/disk: need to add "diskspace" desirable "diskinodes" - it is optional because of "disknodes" are over very rarely. For tag domain/devices/interface: How to describe, if want to add ip addresses for routing network? Also, OpenVZ may move network adapter to VM (for example, eth1), adapter becomes inaccessible on harware node. How to describe it? Is it ethernet type? Thanks! Evgeniy
