[Kimchi-devel] [PATCH v2][Kimchi] Avoid break Wok when register events, if Libvirt is down

When Wok starts up it loads Kimcho model, which tries to register Libvirt events. A problem happens if Libvirt service is down when Wok starts (usually manually/command line start up), because the connection is None, raising an error that breaks Wok. This patch fixes this problem and return a proper log message.
