Re: [Xen-devel] Static domain id's?

[Tim Harris <tim.harris@xxxxxxxxxxxx>]

Domain IDs are allocated within xen, not within xi_create.  

The purpose of DOMID is to hack around the resource assignments that
xenctl makes, telling it to assign the newly created domain the resources
that id 'DOMID' would have originally received.  Similarly, 'max domains'
should be seen as a way of indicating how many sets of these resources
(IP addresses, etc) can be assigned automatically.

As Ian and others have said in the past, we're currently thinking about
a new version of the control tools and so this situation may well change.
One likely approach will be to introduce a proper concept of domain
profiles.  

Cheers,

Tim
