RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Doc Type: Bug Fix

Cause: S4 event was not supported by libvirt on QEMU domains. Consequence: Management applications couldn't know whether guest was suspended to disk or powered off. Fix: Support for S4 event was added. Result: Management applications can now request receiving S4 events.

Description Luiz Capitulino 2012-07-12 14:02:36 UTC 
QMP will soon get support to emit an event when the guest suspends to disk (S4). Libvirt should recognize this event.
Comment 3 Ademar Reis 2012-07-30 20:42:04 UTC 
Do we already have support for the S3 event in libvirt? Otherwise we should either open a new bug or change this one to include the S3 event as well (the event is there in qemu already).
Comment 4 Martin Kletzander 2012-07-31 08:40:13 UTC 
(In reply to comment #3)
Yes, S3 event is already supported in libvirt (since 0.9.11 if I'm right). We are just waiting how the new event will be implemented to modify the code accordingly.
Comment 8 hongming 2012-10-16 10:17:33 UTC 
Because the following result. Change its status to ASSIGNED.

# rpm -q libvirt
libvirt-0.10.2-3.el6.x86_64


# python /usr/share/doc/libvirt-python-0.10.2/events-python/event-test.py

Verify it as follows. The result is expected. So move its status to VERIFIED.
