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 Fangge Jin 2016-04-08 07:09:09 UTC 
Description of problem:
The old logging way(file) is used when no qemu.conf file exists.

Version-Release number of selected component:
libvirt-1.3.3-1.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
0. Log in as non-root user:
$ id
uid=1001(fjin) gid=1001(fjin) groups=1001(fjin) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023

1. $ virsh start rhel7.2
Domain rhel7.2 started

2. $ lsof /home/fjin/.cache/libvirt/qemu/log/rhel7.2-agent.log
COMMAND    PID USER   FD   TYPE DEVICE SIZE/OFF      NODE NAME
qemu-kvm 30098 fjin    1w   REG  253,2     2634 537370310 /home/fjin/.cache/libvirt/qemu/log/rhel7.2-agent.log
qemu-kvm 30098 fjin    2w   REG  253,2     2634 537370310 /home/fjin/.cache/libvirt/qemu/log/rhel7.2-agent.log

3. Touch qemu.conf file:
$ touch /home/fjin/.config/libvirt/qemu.conf

4.
Wait 30s for virtlogd exits or restart virtlogd process. Then
$ virsh destroy rhel7.2
$ virsh start rhel7.2

5.$ lsof /home/fjin/.cache/libvirt/qemu/log/rhel7.2.log
COMMAND    PID USER   FD   TYPE DEVICE SIZE/OFF      NODE NAME
virtlogd 30995 fjin   14w   REG  253,2     5354 537370308 /home/fjin/.cache/libvirt/qemu/log/rhel7.2.log

Actual results:
When no qemu.conf file exists, the old logging way(file) is used.

Expected results:
Virtlogd is used by default no matter whether qemu.conf file exists.

commit 63e2b766a5a704eb19b8bdaeb1cf0fa91f990cb8
Author: Peter Krempa <pkrempa>
Date:   Wed Apr 27 12:58:13 2016 +0200

    qemu: conf: Set default logging approach in virQEMUDriverConfigNew
    
    Instead of setting the default qemu stdio logging approach in
    virQEMUDriverConfigLoadFile set it in virQEMUDriverConfigNew so that
    it's properly set even when the config is not present.
