Hello, I am using domain event notifications from libvirt-event API in my application and it seems to work fine, except for ‘suspend’ and ‘resume’ events where I keep receiving duplicated notifications. Similarly, the example provided with libvirt (in examples/object-events/event-test) also produces twice as much notifications for ‘suspend’ and ‘resume’ than for other events. Here is the sequence of virsh commands and
the output of event-test: Virsh start Fed25 Virsh suspend Fed25 Virsh resume Fed25 Virsh shutdown Fed25 [~/libvirt-3.4.0/examples/object-events] ./event-test qemu:///system Registering event callbacks myNodeDeviceEventCallback EVENT: Node device net_vnet0_fe_54_00_a0_ba_61 Created 0 myDomainEventCallback1 EVENT: Domain Fed25(1) Resumed Unpaused myDomainEventCallback2 EVENT: Domain Fed25(1) Resumed Unpaused myDomainEventCallback1 EVENT: Domain Fed25(1) Started Booted myDomainEventCallback2 EVENT: Domain Fed25(1) Started Booted myDomainEventCallback1 EVENT: Domain Fed25(1) Suspended Paused myDomainEventCallback2 EVENT: Domain Fed25(1) Suspended Paused myDomainEventCallback1 EVENT: Domain Fed25(1) Suspended Paused myDomainEventCallback2 EVENT: Domain Fed25(1) Suspended Paused myDomainEventCallback1 EVENT: Domain Fed25(1) Resumed Unpaused myDomainEventCallback2 EVENT: Domain Fed25(1) Resumed Unpaused myDomainEventCallback1 EVENT: Domain Fed25(1) Resumed Unpaused myDomainEventCallback2 EVENT: Domain Fed25(1) Resumed Unpaused myDomainEventCallback1 EVENT: Domain Fed25(1) Shutdown Finished myDomainEventCallback2 EVENT: Domain Fed25(1) Shutdown Finished myNodeDeviceEventCallback EVENT: Node device net_vnet0_fe_54_00_a0_ba_61 Deleted 0 Note that the 2 lines printed for each event are ok since 2 callbacks are registered in the example. Has anybody else faced this issue? I am using libvirt-3.6.0 on Ubuntu 16.04.
