Description Daniel Berrangé 2010-09-21 14:09:00 UTC

Description of problem:
The use of virConnectListDomains + virConnectListDefinedDomains + virDomainLookupByID/UUID takes O(n) time, and is subject to a race condition. It should be possible to list all domains in a single API call, returning virDomainPtr objects immediately. Likewise for storage pools, volumes, networks, interfaces, node devices.
