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.

Description Ademar Reis 2016-08-24 14:34:30 UTC 
+++ This bug was initially created as a clone of Bug #1369850 +++

The idea is simple: request the OS uptime via qemu-guest agent.

Some patches were submitted to upstream QEMU back in 2015, but never merged (nor reviewed, apparently):

Comment 1 Daniel Berrangé 2016-08-24 15:10:48 UTC 
IMHO this should really be out of scope for QEMU guest agent / libvirt. The guest agent scope is really aimed at providing functions necessary for managing the operation of virtual machine. This is things like CPU hotplug, disk quiesce for snapshotting, and similar things.   Reporting guest OS uptime is getting into the area of managing the guest operating system. That area is absolutely enormous in scope and there are countless existing tools that fill that can role. As such IMHO it doesn't make sense to add uptime reporting into QEMU guest agent, nor libvirt.
Comment 2 Peter Krempa 2016-09-13 08:57:52 UTC 
I agree with Comment 1. This is really getting into OS management scope.
