The problem including a 'config' parameter is that this data becomes totally opaque to the management app. Given a piece of XML describing a domain, including a "config=xxxx' parameter, there's no way for the app to find out what the underlying resources settings are. > >For the filesystem stuff, for LXC we've got a section under <devices> > >whcih looks like > > > > <filesystem type="mount"> > > <source dir='/some/path'/> > > <target dir='/'/> > > </filessytem> > > > >Which says 'make /some/path be the root filesystem, using a bind mount'. > > > >I could imagine representing the idea of a template with a slight > >variation like > > > > <filesystem type="template"> > > <source name="template name"/> > > <target dir='/'/> > > </filesystem> > > > Yes, we can. But template name is not property of file system. Well, actually I'd argue that it is. The "source" element refers to the resource in the host OS that forms the source of the filesystem. So for a root filesystem instantiated from a template, I think template name is the most applicable. > >>For tag domain/devices/interface: > >>How to describe, if want to add ip addresses for routing network? > > > >We'll probably want todo something based on <interface type='ethernet' > >which is a generic catch all config. > > > >Does OpenVZ support bridging, or NAT for containers ? > bridging is supported. > NAT can be configured via iptables. If it supports bridging that is sufficient. The libvirt networking APIs, allow us to implement NAT for any VM in terms of the generic bridge support. Basically libvirt creates a bridge device 'virbr0' and sets up NAT rules for that device. A guest VM simply needs to be connected to virbr0, and then NAT automagically works for it.
