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.

Fixed In Version: libvirt-0.9.4-5.el6
Doc Type: Bug Fix
Doc Text:
Cause: Error checks on early libvirtd startup did not report errors verbosely. Consequence: Broken configuration file or other early errors while libvirtd was starting up caused the daemon to exit silently only setting the process return value to indicate error. This confused the users, as no message was printed and the process return code has to be checked manualy. Fix: Error handling messages were added to the early start phases of libvirtd. Result: Errors during start are now printed and logged.

Red Hat Product Errata RHBA-2011:1513 0 normal SHIPPED_LIVE libvirt bug fix and enhancement update 2011-12-06 01:23:30 UTC

Description Dave Allan 2011-08-06 04:38:04 UTC 
Starting libvirtd with a configuration file containing an unterminated string for log_outputs causes libvirtd to exit silently.

After adding the following to libvirtd.conf

log_outputs="1:file:/var/log/libvirt/libvirt_debug.log

libvirtd, even when started from the commandline with -v, exited silently; nothing in the logs, nothing on stdout to indicate what was wrong.
Comment 4 dyuan 2011-08-23 09:18:55 UTC 
Verified PASS with libvirt-0.9.4-5.el6, reproduced this bug with libvirt-0.9.4.4.el6.
