To make sure I understand the API. If I have a domain defined, but not
started.. it will show up in the list returned by:
virConnectListDefinedDomains
but not in the list
virConnectListDomains
Conversely, if it is started... it will only be in the list:
virConnectListDomains
not in the list
virConnectListDefinedDomains
Is that correct?

Yes, that's the correct behavior of these functions.
virConnectListDefinedDomains list domains that are inactive but
defined and virConnectListDomains lists domains that are active.
If you combine the output of both functions then you get the complete
list of domains libvirt knows about for a given host.

list of domains libvirt knows about for a given host.
Modulo the obvious race condition where a guest starts/stops in between
the time you call those two functions :-)
One of these days I'll have time to add an API I've long wanted - one
that lists all domains, and returns the virDomainPtr objects directly
virConnectListAllDomains(virConnectPtr conn, virDomainPtr *domains, int *ndomains);
where libvirt allocates 'domains' to be the right size, not requiring
the caller todo so. Similarly this same API pattern for all other objects
virNetworkPtr, virStoragePoolPtr, etc, etc

This would be _really_ appreciated :)
