If this gets implemented I would suggest a call that fetches all domains from a running system and not only the defined or only the active ones.
This is a good idea regardless. The current APIs require an application todo
num = list number of domains for 1 to num lookup domain by id
In the case of the Xen drivers, this requires O(n) calls to XenD which are rather expensive. XenD does actually have ability to return data about all domains in a single request. So if we had an API for fetching all domains at once it'd only require O(1) expensive XenD calls. I'd imagine something like this
int virConnectListAllDomains(virConnectPtr conn, virDomainPtr **domains, int stateflags);
I've thought about something similar as well. It would also be useful to have a command like ListUUIDs with similar state flags, giving apps a more light weight manner of polling for domain state changes (ex. virt-manager) - Cole
