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-8.0.0-5.6.module+el8.6.0+17751+d6559882
Doc Type: Bug Fix
Doc Text:
Cause: The reply from the guest agent doesn't contain one of the fields when running on windows. The code reports a spurious log entry in such case. Consequence: A safe-to-ignore error log entry is produced, in many times repeatedly. Fix: The code was modified to avoid reporting the error.

Comment 2 Lili Zhu 2023-01-08 14:15:57 UTC 
Verify this bug with:
libvirt-8.0.0-10.2.module+el8.7.0+17753+6a6ae27a.x86_64

1. prepare a win guest with guest agent device
# virsh domtime win2k19 
Time: 1673137042

2. config the libvirtd conf file
# grep -v ^# /etc/libvirt/libvirtd.conf 
log_outputs = "3:file:/var/log/libvirt/libvirtd.log"

3. restart libvirtd

4. monitor the log in one terminal
# tail -f /var/log/libvirt/libvirtd.log 

5. Get guest disk info in another terminal
# virsh guestinfo win2k19 --disk 
disk.count          : 1
disk.0.name         : \\.\PhysicalDrive0
disk.0.partition    : no
disk.0.serial       : QM00001

6. check the log
# tail -f /var/log/libvirt/libvirtd.log 
(no more output)

As the testing result matches with the expected result. Mark the bug as verified.
