Re: [Libvir] Request for additional entry points

I'd actually question whether libvirt should have any concept of 'passive' or 'inactive' domains at all. Just to play out a few scenarios:

* Definitions of inactive domains are stored on a remote server, libvirt has no visibilty into this system. virDomainSetConfig() would not help since there is no concept of a domain being inactive on a single host, rather inactive domains can be deployed to any host in the server farm at will. * Definitions are visible on the local filesystem, but this FS is shared NFS / SAN storage. Again while their config files may be technically visible via the shared filesystem, there is no meaningful association between an inactive config & a host. * Domains are created from config 'templates'. The template defines a generic resource configuration, turned into a fully fledged config on-demand - perhaps with the variables plugged into the template coming from an alternate datastore (SQL databsae perhaps). In this case there would be no sense in storing pre-made XML configs, since the master info is a combo of the template & SQL database entries.

So, really the only case where there is any meaningful concept of 'passive' domain configs associated with a static single host model - for example that provided by XenD which happen to have a simple store of inactive domains in /etc/xen.

Thinking about what tools might need information on inactive domains: - Desktop management tool - cf VMWare Workstation. Possibly, but even here there is no reason such a tool represents inactive domains in terms of a libvirt XML config file. It may well have generic templates eg 'Linux Web Server and instances 'web0.google.com', 'web1.google.com', 'web2.google.com', where the only instance specific data is the hostname and master disk image. - Data center management tool - it may well have a concept of inactive domain configs, but it almost certainly won't be associated with a single host, so unlikely to be asking libvirt to list inactive domains.
