Re: [libvirt] some unsorted questions

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); The 'stateflags' parameter would be a bit-field where each bit corresponded to one of the virDomainState enumeration values. The 'domains' list would be allocated by libvirt, and filled in with all the domain objects, and the total number of domains as the return value.
