Re: [libvirt] [PATCH] Improve some error messages about unsupported APIs/URIs

If there is no driver for a URI we report "no hypervisor driver available" This is bad because not all virt drivers are hypervisors (ie container based virt). If there is no driver support for an API we report "this function is not supported by the hypervisor" This is bad for the same reason, and additionally because it is also used for the network, interface & storage drivers.
