Hi Daniel,
I didn't realize that I even did not follow the manner of XML.
I have worked with this problem and got a small patch to handle "ID"
in OpenVZ functionality.
I found it is working well with the XML script included "ID" in domain
tag.
I am concerned that I had to edit the common file domain_conf.c.
I still believe I should keep it away from this problem for
compatibility with the others.
How do you think can I avoid this?
The 'id' value is not intended to be settable by the end user,
which is why the domain_conf.c parser does not parse it by
default.
So for your usage in OpenVZ, you'll need to auto-assign an 'id'
value when creating a new guest. eg, get a list of existing
OpenVZ guest 'id' values and then pick the first one which is
not used.

This is where you need to pull in an auto-assigned ID value
instead of using vmdef->id.

Daniel
