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.
Best regards,
Antoine
