We want to convert over to server-side events, even for older APIs. To do that, the client side of the remote driver wants to distinguish between legacy virConnectDomainEventRegister and normal virConnectDomainEventRegisterAny, while knowing the client callbackID and the server's serverID for both types of registration. The client also needs to probe whether the server supports server-side filtering. However, for ease of review, we don't actually use the new RPCs until a later patch. * src/conf/object_event_private.h (virObjectEventStateCallbackID): Add parameter. * src/conf/object_event.c (virObjectEventCallbackListAddID) (virObjectEventStateRegisterID): Separate legacy from callbackID. (virObjectEventStateCallbackID): Pass through parameter. (virObjectEventCallbackLookup): Let legacy and global domain lifecycle events share a common remoteID. * src/conf/network_event.c (virNetworkEventStateRegisterID): Update caller. * src/conf/domain_event.c (virDomainEventStateRegister) (virDomainEventStateRegisterID, virDomainEventStateDeregister): Likewise. (virDomainEventStateRegisterClient) (virDomainEventStateCallbackID): Implement new functions. * src/conf/domain_event.h (virDomainEventStateRegisterClient) (virDomainEventStateCallbackID): New prototypes. * src/remote/remote_driver.c (private_data): Add field. (doRemoteOpen): Probe server feature. (remoteConnectDomainEventRegister) (remoteConnectDomainEventRegisterAny): Use new function. Signed-off-by: Eric Blake <eblake@redhat.com>
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.
