In order to mirror a server with per-object filtering, the client needs to track which server callbackID is servicing the client callback. This patch introduces the notion of a serverID, as well as the plumbing to use it for network events, although the actual complexity of using per-object filtering in the remote driver is deferred to a later patch. * src/conf/object_event.h (virObjectEventStateEventID): Add parameter. (virObjectEventStateQueueRemote, virObjectEventStateSetRemote): New prototypes. (virObjectEventStateRegisterID): Move... * src/conf/object_event_private.h: ...here, and add parameter. (_virObjectEvent): Add field. * src/conf/network_event.h (virNetworkEventStateRegisterClient): New prototype. * src/conf/object_event.c (_virObjectEventCallback): Add field. (virObjectEventStateSetRemote): New function. (virObjectEventStateQueue): Make wrapper around... (virObjectEventStateQueueRemote): New function. (virObjectEventCallbackListCount): Tweak return count when remote id matching is used. (virObjectEventCallbackLookup, virObjectEventStateRegisterID): Tweak registration when remote id matching will be used. (virObjectEventNew): Default to no remote id. (virObjectEventCallbackListAddID): Likewise, but set remote id when one is available. (virObjectEventCallbackListRemoveID) (virObjectEventCallbackListMarkDeleteID): Adjust return value when remote id was set. (virObjectEventStateEventID): Query existing id. (virObjectEventDispatchMatchCallback): Require matching event id. (virObjectEventStateCallbackID): Adjust caller. * src/conf/network_event.c (virNetworkEventStateRegisterClient): New function. (virNetworkEventStateRegisterID): Update caller. * src/conf/domain_event.c (virDomainEventStateRegister) (virDomainEventStateRegisterID): Update callers. * src/remote/remote_driver.c (remoteConnectNetworkEventRegisterAny) (remoteConnectNetworkEventDeregisterAny) (remoteConnectDomainEventDeregisterAny): Likewise. (remoteEventQueue): Hoist earlier to avoid forward declaration, and add parameter. Adjust all callers. * src/libvirt_private.syms (conf/object_event.h): Drop function.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
