FWIW, for the initial 'virConnectOpen' API I think it probably would be worthwhile us supporting a standardized "timeout" URI parameter. That way if the remote service doesn't respond at all for some reason users can have fine control. That's a sufficiently targetted use case that it'd be easy to do, compared to timeouts for arbitrary APIs.
Indeed - having a timeout on the initial connection attempt is much more useful than worrying about individual APIs when you have a responsive connection, since it is the indeterminate time of establishing a remote connection that may be the problem here. But does that mean yet another C API? We already have virConnectOpen{,ReadOnly,Auth}. Or are you envisioning this just in the language bindings (Java, python - but not C)? -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
