Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.

qemu: Revert to blocking behavior of qemuAgentCommand
Before commit 05447e3af44ec153314ff97cd611330d9b4b5730, qemuAgentCommand
blocked until it got a reply or appropriate event. When new parameter
was added to qemuAgentCommand in the above commit, all existing callers
of it were updated in a wrong way changing them from blocking to
5-seconds timeout.

qemu: Remove redundant parameter from qemuAgentSend
The @timeout parameter of qemuAgentSend is both redundant and confusing.
This patch should not result in any functional changes.

[root@zhpeng ~]# virsh dompmsuspend rhel63 --target disk
Domain rhel63 successfully suspended
[root@zhpeng ~]# virsh start rhel63
Domain rhel63 started
[root@zhpeng ~]# virsh shutdown rhel63 --mode agent
Domain rhel63 is being shutdown
[root@zhpeng ~]# virsh start rhel63
Domain rhel63 started
