When domain is reverted to a snapshot it's configuration and state may be changed. If the domain state was changed libvirt emits one or more <NEW STATE>_FROM_SNAPSHOT events. In case when domain and target states both are offline there will be no state changes and no events. Lack of the event become a problem for virt-manager https://bugzilla.redhat.com/show_bug.cgi?id=1081148 This commit adds DEFINED event emission in this signle case and only if snapshot have the domain configuration. --- src/qemu/qemu_driver.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index a762521..1fb41e3 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -15179,7 +15179,7 @@ qemuDomainRevertToSnapshot(virDomainSnapshotPtr snapshot, VIR_DOMAIN_SNAPSHOT_REVERT_FORCE, -1); /* We have the following transitions, which create the following events: - * 1. inactive -> inactive: none + * 1. inactive -> inactive: EVENT_DEFINED if snapshot has config * 2. inactive -> running: EVENT_STARTED * 3. inactive -> paused: EVENT_STARTED, EVENT_PAUSED * 4. running -> inactive: EVENT_STOPPED @@ -15465,6 +15465,12 @@ qemuDomainRevertToSnapshot(virDomainSnapshotPtr snapshot, VIR_DOMAIN_EVENT_SUSPENDED, detail); } + } else if (config && !event) { + /* Transition 1 */ + detail = VIR_DOMAIN_EVENT_DEFINED_FROM_SNAPSHOT; + event = virDomainEventLifecycleNewFromObj(vm, + VIR_DOMAIN_EVENT_DEFINED, + detail); } break; -- 1.8.3.1 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
